Writing Quantum Computer Code

Seems inevitable that quantum computers will be available in much greater capacity than the current cloud-based offerings from Alibaba and IBM, amongst others. Meanwhile, realization is setting in that coding these wonders is different than coding classical computing systems. Microsoft has Q#, there is qHiPSTER and QISKIT to name several languages. Google is leading the development of OpenFermion, available at GitHub and a complete offering through PyPI. April 1, 2018.

Cryptography, Quantum Computing, and the Post-Quantum Computing Era…

We’re not even at a really useable quantum computer in the commercial world at this point in history. When we get there, what will the computing age be like? In a post-quantum computing era, the world of cryptography will have been rocked. Will consulting firms see a rush of the sort seen during Y2K? What will become of cryptocurrency? Will the first users of the quantum supreme system get the loot and scoot? Take a quick read of this editorialist’s ideas. They may not be far off the mark and are likely in tune with the reason The Qubit Report was founded: “To keep an eye on the state of the quantum computing industry so you know what’s going on”.

China: Closed the Technological Gap

U.S. Government investment in quantum computing research sits at $200M per year. China has announced plans to complete its $10B national quantum computing centre by 2020. Why the concern? Because quantum computing is coming and it may break encryption currently deemed unbreakable by classical computers; alter the financial, agrcultural, and chemistry industries with as-yet-unknown ability to calculate results from big data; and enable unbreakable communication security. Though the U.S. may be excelling in quantum hardware, China, as evidenced by patent applications, is focused on software, at least for now, but is poised to take the leap into the lead overall.

Quantum Computers as an Instrument of Oppression?

The politics aside, this essay poses some serious questions for the future of humanity given the arrival of quantum computing. The piece draws parallels to George Orwell’s 1984 but in place of friends turning on one-another, our own data is used against us. Consider the electronic trail we all leave daily, from our personal devices to the speed cameras and ubiquitous video cameras. These devices produce endless data about everyone and everything. It is being amassed. It is impossible to sort through; at least for the time being. How will life be when the petabytes upon petabytes of data are analyzed, or at least assisted by, quantum computers? Looking past the politics, the thoughts provoked are captivating. Qubit.

Entangling Record

Attaining quantum supremacy demands a large number of controllable qubits. Physicists at the Austrian Academy of Sciences with collaboration from others in academia have created measured entanglement between groups of qubits. Distinction must be made that the entanglement is not between individual particles but groups. The multi-particle entanglement was attained and measured using new detection techniques. Potential application to quantum computing is derived from the qubits being able to be addressed and read individually. This team hopes to reach their next milestone of 50 entangled particles. April 15, 2018.

Reducing the Co$t of the Qubit

Quantum computing research would not be possible without large grants from governments. Global corporations such as IBM, Google, and Alibaba, conduct their own research and development funded from their own coffers. The current cost of quantum computing devices is far too high for the commercial market to take off. Significant cost reductions may be on the horizon. The TOLOP project, developed in-part to keep Moore’s law true, has produced transistor component reduction tests which apply to quantum computing. In the tests, the transistors being studied were operated as qubits. If the manufacturing of these special transistors could be mass produced using the current transistor production technologies, it is conceivable the qubit resistors could use the same mass production processes. Ergo, qubit costs tumble, commercial qubit market comes to life. April 21, 2018.

End-to-End Quantum Transmission, On-demand

Yale researchers are playing ball, baseball, sorta, with qubits. Akin to clustering classical computers, the approach networks quantum systems and their qubits. Similar to a classical network, the qubits being fired (pitched) must be coordinated with the receiving end (caught) or else risk overwhelming the catcher. Therein lies the benefit of the study — bringing the pitch and catch into synchronized send-and-receive, on-demand. More has been discovered and researched, read on for further details.

Quantum Computing Utilizing Microwave Photons

High-precision instrumentation has been shown to measure the arrival of microwave photons sans destroying the quantum information encoded. The Swiss Federal Institute of Technology and University of Tokyo have shown the detection of the photon’s arrival via its cavity-qubit reflection. Though not a completely new concept, use of microwave photons has previously ended with the detected photon destroyed. Enter quantum non-demolition, or QND. With continued research, the end-result could be microwave quantum computing enabled completely by photons. April 23, 2018.

“Quantum non-demolition detection of propagating photons is achieved using a transmon circuit (a superconducting qubit) inside a microwave cavity. The cavity mediates an entangling interaction between the transmon and the propagating microwave field. Here, the reflection of a single photon off the cavity imparts a 180° rotation on the qubit state, which is represented as an arrow in a spherical phase space. The change in the state of the qubit can be determined from a later rotation and projective readout”. (Image Credit: APS/Alan Stonebraker)
