Is your brain a quantum computer? A group of researchers from around the globe has funding to study the human brain’s potentially quantum computing processes. It is thought that the key to long term memories is at the quantum level. Knowing quantum computers require ultra-cold and stable environments would make the brain’s 98.6 degrees F, humid environment, an unlikely place to find quantum mechanics at play. An assertion within the study is that the spin at the atmoic nuclei are an exception to the cold and stable requirement. The Quantum Brain Project, or QuBrain, is getting underway. Read on. March 28, 2018.

Australia’s Quantum Computer Engineer Shortage
With Australia vying for the global lead in quantum computing, recent quantum computing academy hubs and center openings have made the need for capable students to fill those facilities clear. It has become quite obvious the lack of a qualified pool of prospective personnel (i.e. qualified students) places higher risk of failure on the Aussie quantum gamble. The New South Wales government supports the Quantum Academy for its described purpose of creating the quantum computing engineers to drive the industry in Australia. What is needed are part quantum physicist, part auto-mobile mechanic, students. This report sheds some light on a critical, non-technical piece to the budding quantum computing industry Down Under.

Qudits vice Qubits. More Ways to Store Information in a Photon.
Quantum information science has been built on such experiments involving quantum communication, quantum cryptography, and numerous other facets of this newly burgeoning field.

This report discusses many aspects of the qudit — a high-dimensional quantum system based on the Orbital Angular Momentum (OAM) state of photons and the application to quantum information science. March 12, 2018.
The Basic Principles
“It might be a good idea if all of us were to make a late New Year’s Resolution to take a fresh stab at grasping quantum’s basic principles.” We at The Qubit Report have a tough time understanding all of the wide and varied facets of quantum. We are in good company with the author of this article who makes an attempt at explaining why this difficulty exists. Predominantly, the blame is placed square on lack of a need to know — for our survival.

India To The Rescue?
When Y2K was upon us, there was ample warning and a definite countdown to, well, Y2K. But what about the arrival of quantum supremacy and the breaking of encryption algorithms ? Quantum is coming (Q2K). What if Q2K is 5 years away? Are we ready? Will we be ready? What if it is sooner? The Hindustan Times postulates the West will be knocking at the door of Indian IT to solve the Q2K problem. Because quantum is coming, we just don’t know when.

Projects the $636 Million Could Fund…
Frontier, El Capitan, Aurora are all exascale projects which may be funded with the passage of a $636 budget for the U.S. Department of Energy (previously reported here at The Qubit Report). Though $636 million is a hefty sum, a scant $105 million is slated for quantum information science and its derivatives.

An Aid to Quantum Communication Encryption Spoofing Detection?
A team of researchers have determined how to tell apart beams of entangled photons. By slowing one beam and having them rejoin, the frequencies of the light combine showing a marked peak in frequency. The closer in time the two beams arrive, the lower the peak and the demonstration of better efficiency. That is the crux of the study. The results lend to more assured encrypted communication channels. One potential use in encrypted communications security is that any interference from a nefarious actor could cause a marked peak and thus reveal potential tampering. Interesting read. March 4, 2018.
Fear the Gap
The number one threat posed by quantum computing’s day of arrival is the theoretical ability to crack the code on public key cryptography. Presuming nation-states will have the technology first, if we, the public, have not strengthened our cryptographic systems with longer keys and quantum-resistant algorithms, to keep it simple, the threat will span public-key, symmetric, and hashing cryptographic functions. Much to do and a long way to go in this race with a not-so-certain finish line.
Widespread Data Theft Looming?
With quantum computing edging closer and closer, the necessity to find alternative encryption systems resistant to quantum computing attacks is needed. PQCRYPTO is a European effort hemmed together between academia and commercial entities. They are brainstorming methods to prevent widespread data decryption, our word for ‘data-theft with quantum computing’. Presently, asymmetrically encrypted data streams, if captured, may be decrypted at a future date. Think about it; read on. March 6, 2018.
China’s Quantum Ambitions (…and AI, too)

With billions of dollars invested to date, the Chinese are working feverishly to attain the quantum computing lead. Military and economic ramifications pose a real threat to U.S. and other nations’ superiority over China. Well worth an extra moment to take in this article. March 2, 2018.
We Lack Natural Intuition for Quantum Systems
Quantum physics is alien to our physical world and so many shy away from the concept as “bizarre”. Apparently, teams of physicists have managed to create a relationship between the physics of matter and particle physics. Dubbed the “Higgs mode”, this link between the two is all-to-do with quantum phase transition. Take a few moments to let this one sink in.
U.S. Congress Chasing Chinese Quantum Efforts with Dollars
We’ve reported on quantum computing expenditures by various governments and agencies throughout the world. A positive sign for the U.S. is Congress’ proposed legislation significantly increasing funding and enabling the National Quantum Initiative (NQI). The proposed NQI would bring government, academia, and industry together to maintain the U.S. edge in quantum computing.
Financial Sector Considerations for Quantum…
This piece found at Risk.net puts forth a fairly broad discussion concerning the financial sector’s need for preparation for the advent of quantum computing.

Using More Than Polarization to Encode Photons…
Qubits, quantum bits, are photons manipulated to encode data. Predominantly, the photons are encoded in a binary sense. Increasing the qubit data capacity is challenging. However, there is promise in increasing the variance beyond that of binary encoding. Experimental, high-dimensional qubit encoding is nascent, to say the least. However, this team from Tsinghua University, Beijing, has developed a multi-dimensional quantum system with some promise to speed up the quantum internet.
How to Prove Quantum Entanglement…
For many, understanding how quantum computers work is left as an “I believe” moment. But this begs another question for those that try to understand: How does one know a quantum computer is “entangling” as it is theorized? Scientists at the Univeristy of Belgrade and the University of Vienna have developed a method to prove quantum entanglement — the basis of quantum computing.
Better Cryptography, Sure. But Necessary?
Quantum computing is edging closer. The National Institute of Standards and Technology is reviewing 65+ alogirthms for quantum-resistant attributes. This is in an attempt to stave off what could be considered catastrophic damage if quantum-resistant alogrithms are not found, tested, and implemented before the advent of quantum computers.
Silicon Spin Qubits…On a Chip…
At this nascent stage in the [prospect] of quantum computers, we at The Qubit Report feel it is right to put forth what may be construed as advertising. However, if one takes a look at the research, the how, and the why at this early stage in QC, we find it is almost an imperative to put forth what we find. Take a read into this report. It speaks for itself as to why Intel is following this parallel approach into the race for quantum supremacy (in contrast to Big Blue’s path).
