Quantum Mechanics, Consciousness, Measurement, Nature

Perhaps it is a good time to put some deep thought into what the implications of quantum mechanics might be. We know, in the world as we perceive it, quantum is counterintuitive. But quantum has been proven to exist: quantum superposition quantum mechanical entanglement. Both are real, but are they? What part does measurement play? What part does consciousnesses have in quantum mechanics? A bit of a stretch from the typical quantum computing article, this piece is quite thought provoking and begs many questions about reality.

Theoretically, This Quantum Computing Method is 10 Billion X More Tolerant…

Researchers in Japan have theoretically met the challenge of errors caused by noise in qubit production. Reduction of the noise is attained through a type of ‘squeezing’ applied to light. Their model delivers 10 billion times the resistance to errors than alternate models. June 2, 2018.

Japanese research teams theorize reducing errors in quantum systems is possible up to a 10 billion times reduction.

Are We Close, Yet?

We see and hear the question asked often…how close are we to a true quantum computer? The question is difficult to answer. The Qubit Report has seen anywhere from 3 years to 10 years and some predictions out to 20 years. (Naysayers say ‘never’, of course). There are many reasons precluding this complicated technology from coming to fruition right-away. Noise, electrical flux, maturity of qubit hardware, lack of quantum algorithms, and funding to name several. This piece in Scientific American does a fine job of looking at the “When, really?” question explaining these challenges and many others. June 2, 2018.

Quantum Supremacy or Quantum “Not Enitrely Useless”?

Keep reality in perspective. Quantum supremacy is a popular term will it come to fruition? We at The Qubit Report believe quantum computing will get here sooner or later. But keep all angles in mind. This author puts forth an argument that quantum will likely never arrive. Entropy begets more entropy. Noise begets more noise. But is it all worthless? Well, read on. Worth a couple minutes.

Quantum Measurement Communication Speedup

A research team from Bar Ilan University in Tel Aviv has managed to implement a method of quantum communication measurement which greatly increases the rate at which quantum measurement data is transferred. Quantum encryption secrecy relies on the ability to determine if a man-in-the-middle attack (eavesdropper) has infiltrated the communication channel between two parties. The ability for the parties to maintain secrecy relies upon measurements of the quantum communication link coupled with the speed at which the measurements are transferred. Present methods utilize electrical paths – a megahertz to gigahertz bottleneck. The team replaced the electrical method with an optical method which provides a multi-fold speed increase for the data transfer in comparison to the electrical method. June 4, 2018.

Why the Threat to Bitcoin from Quantum Computing is Fixable.

The Qubit Report is carrying an article titled “The Russians and Blockchain…”, today. Coincidentally, THE EPOCH TIMES has a piece describing the threat and the solution to blockchain security. It’s held that the advent of quantum computing will usher in signature-cracking by 2027. The threat to blockchain boils down to: (1) After a Bitcoin (a cryptocurrency) transaction is broadcast to the network, it is at risk. (2) Using a quantum computer, the secret key could be derived before transaction placement on the blockchain. (3) Malicious intent could permit the broadcast of the secret key with a new transaction to the malicious actor’s own benefit. (4) Placing the new stolen secret key-enabled transaction on the blockchain before the original transaction permits grand theft of all the bitcoin “behind the original”. The piece continues on, pointing out 4 solutions to the issue with seemingly ample time for their implementation. Let’s hope the 4 solutions and the time allotted are sufficient. And the world listens. June 5, 2018.

Phonons and Photons; Big Vibrations

Photons are the quantum of light. Phonons are the quantum of sound. Studies at the Vienna University of Technology are suggesting the use of phonons to transfer quantum information. Testing is being conducted with diamond rods containing silicon placed in specific locations around carbon. By vibrating the rod, the silicon atoms form a needed quantum-mechanical bond. Through use of microwaves, the silicon is turned off and on, emitting or absorbing phonons. The resulting quantum entanglement permits quantum information to be transferred. June 6, 2018.

Because Quantum is Coming; But When Will It Be Tamed?

Quantum computing is coming. When and how powerful is tough to pin down. The Qubit Report carried a piece calling quantum computing “a bunch of bunk”. For one, it’s not here. The media hype helps fundraising for research and the stories of doom and gloom abound throughout the mainstream media because it sells. That’s it. We do know this: Quantum computing at a practical level is a bit in the distance. Semiconductor technology will keep advancing classical computer power, reducing some of the processing gain through quantum computers.

Error Correction Not Needed

Israeli led researchers at the Weizman Institute of Science have presented evidence for particles capable of storing quantum information — without needing error correction. These particles are termed non-Abelian anyons. Standard particle physics entails only fermions and bosons. However, exceptions do occur, called anyons. Abelian anyons are akin to fermions in behavior. Non-Abelian anyons have ‘odd’ properties useful, it is thought, for topological quantum computing (TQC). TQC does not demand error correction to make the qubits useful. Why no error-correction needed? Locally, perturbations of the anyons may exist but the errors do not map globally where it matters.

Qubit Control thru Silicon and Magnetism

Silicon-based qubits have spin-orbits which are manipulated with magnetic fields more readily than other means available. Designers from the University of Wisconsin-Madison created the experimental device, based on silicon. Research scientists from Purdue University and the Technological University of Delft conducted the experimentation. The spin-orbit strength was found to be dependent on magnetic fields from external sources coupled with the silicon surface material; where qubits reside as quantum dots. Control of the qubits can thus be controlled in-part through control of the magnetic field. This capability lends quantum computing a boost which is needed for overall quantum information system control. June 9, 2018.

Microsoft, OpenVPN, Post-Quantum Computing

Recently, Microsoft made virtual private networks (VPNs) and post-quantum cryptography (PQC) cryptosystem experimentation available for public study. Making use of the widely acclaimed OpenVPN software, MS combined OpenVPN with a PQC kit. The present iteration only protects data tunneling between the client and the VPN server with purportedly PQC-safe encryption algorithms. As data exits this trusted network onto the internet (public), classical cryptography takes over the encryption, increasing risk to the data’s confidentiality.

Superconducting Qubit Transferred Via Coaxial Cable

Physicists at the Swiss Federal Institute of Technology in Zurich, Switzerland, have successfully transferred two qubits via coaxial cable. Using a microwave photon resonator to transmit the qubit state, the quantum state was successfully transmitted to a second qubit through the cable; a distance of about 2 meters. With a transmission success rate of 80 percent, the process was repeatable upwards of 50,000 times per second. The team’s next goal is to enable entanglement swapping – using qubits to transmit and receive. If successful, the technique could open up avenues for larger quantum computers. June 18, 2018.

Intel’s Direction

It is no secret Intel is all-in for producing quantum computers. They have the infrastructure to mass produce computer chips. Now, if they could get a quantum chip to fit into this production line what else could there be? Many sizeable – and frigid – challenges remain. However, as Intel’s Director of Quantum Hardware, Jim Clarke, reminds us, the quantum computing system not only requires super-cooling refrigeration, the devices must have circuit boards, RAM, long-term storage, essentially, high-powered computers based-on silicon to interact with the qubit wafer. He goes on to recall the size of the Cray supercomputer a scant 40 years ago. It filled a room; over the past 40 years, systems with similar computing power shrank to fit in our hands.

Quantum Random Number Generation

In encryption, the one-time pad is known as the most secure method to maintain confidentiality of data — unbreakable with completely random numbers. Acting as the cryptographic key, random numbers must be truly random or the risk to the encrypted data becomes an issue. Third-party knowledge of the underlying algorithm presents opportunity for exposure of the keys. Alternate random number generating processes are influenced by the laws of physics and latency of generation. Enter quantum physics; a space where there is ample chaos to generate truly random numbers. “If you take two photons emitted by the same atom at different times but under the same conditions, they may exhibit different behaviors, and there’s no way to predict those behaviors ahead of time.” Current approaches, commercial sources, and history of the quest for random number generation is found in IEEE Spectrum’s “The Future of Cybersecurity Is the Quantum Random Number Generator”.
