Scientists have demonstrated entanglement and two-particle interference with phonon using an acoustic beam splitter.
Quantum computing is very expensive due to the super conductors that are needed are activated at very cold or very hot temperatures. There are technologies posted on this blog that is closer to room temperature, but not quite there. Thus looking at the problem differently is by looking at phonons. Thus the following was provided by interestingengineering.com written by Tejasri Gururaj where the following was provided about this subject:
"Phonons are to sound what photons are to light. Photons are tiny packets of energy for light or electromagnetic waves. Similarly, phonons are packets of energy for sound waves. Each phonon represents the vibration of millions of atoms within a material.
Both photons and phonons are of central interest to quantum computing research, which exploits the properties of these quantum particles. However, phonons have proven challenging to study due to their susceptibility to noise and issues with scalability and detection.
Now, in a breakthrough study, scientists have successfully split phonons paving the path for a new type of quantum computer called linear mechanical quantum computers.
The research led by Prof. Andrew Cleland from the Pritzker School of Molecular Engineering (PME) at the University of Chicago demonstrated two experiments using an acoustic beamsplitter to split the phonons.
This helped them observe two fundamental quantum phenomena previously only seen in photons.
Beam splitter with single phonons
Splitting, in the context of quantum computing, refers to the ability to manipulate and control quantum states.
In their experiments, the scientists employed phonons with frequencies far beyond the range of human hearing. For the first of the two experiments, the team used the acoustic beam splitter to split a phonon.
Upon entering the beam splitter, the phonon entered a superposition state, simultaneously being transmitted and reflected. This happens due to a phenomenon known as interference.
To preserve the superposition state, the phonon was captured in two qubits. Qubits are the basic units of quantum information analogous to bits in classical computers.
The information about which qubit captured the phonon is unavailable until a measurement (or observation) is performed on the system. This causes the superposition state to collapse, revealing the information.
Before measurement, the phonon's presence was spread across both qubits, demonstrating the characteristic of quantum superposition. But, measuring the two-qubit superposition revealed a phenomenon central to quantum computing called entanglement.
Entanglement refers to a correlation between two or more qubits, such that the state of one qubit depends on the state of the others, even when physically separated, and cannot be described independently.
Two phonon interference
For the next experiment, the team wanted to demonstrate the Hong-Ou-Mandel effect, which was first seen with photons in the 1980s. When two identical photons are transmitted in opposite directions into a beam splitter simultaneously, they interfere. The superposed state is such that the two photons are found traveling together in the same direction.
The team showed that when two identical phonons were sent into a beamsplitter simultaneously, the superposed outputs exhibited interference, resulting in the two phonons always being detected together in one of the output directions
This effect, known as two-phonon interference, provided evidence that both phonons were traveling in the same direction despite the qubits' inability to capture two phonons simultaneously.
Both experiments were conducted at exceedingly low temperatures and employed surface acoustic wave phonons on lithium niobate, a material conducive to quantum phenomena.
The demonstration of two weird or spooky quantum phenomena with phonons was exceptional. Harnessing the quantum properties of entanglement and superposition with phonons is essential for building linear mechanical quantum computers.
These computers could open avenues for all kinds of new computations. In a press release, the lead author of the study, Cleland said, "The success of the two-phonon interference experiment is the final piece showing that phonons are equivalent to photons. The outcome confirms we have the technology we need to build a linear mechanical quantum computer."
The findings of the study are published in the journal Science.
Study abstract:
Linear optical quantum computing provides a desirable approach to quantum computing, with only a short list of required computational elements. The similarity between photons and phonons points to the interesting potential for linear mechanical quantum computing using phonons in place of photons. Although single-phonon sources and detectors have been demonstrated, a phononic beam splitter element remains an outstanding requirement. Here we demonstrate such an element, using two superconducting qubits to fully characterize a beam splitter with single phonons. We further use the beam splitter to demonstrate two-phonon interference, a requirement for two-qubit gates in linear computing. This advances a new solid-state system for implementing linear quantum computing, further providing straightforward conversion between itinerant phonons and superconducting qubits."
So do you think this is a good approach?
I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP

As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
