Google and NASA Contracting Bristlecone’s Quantum Computing Services. Google is in contract with NASA to test for quantum supremacy of its Bristlecone 72-qubit quantum computer. Due to the quantum computer’s inherent environmental challenges, the NASA team will connect via cloud services for software and quantum circuit development. The results from the Bristlecone runs will be compared in July of 2019. The comparison will be to those resulting from the NASA supercomputer, Pleiades. Pleiades, a classical computer albeit one of the top 25 supercomputers in the world, will simulate the quantum circuits found in Bristlecone. Ergo, we should be able to discern if Bristlecone, a 72-qubit quantum computer, outperforms Pleiades, a classical supercomputer design. Reference is MIT Technology Review…

Protecting Entanglement of Photons with Symmetry. Research conducted at the Karlsruhe Institute of Technology further proves quantum entanglement (quantum states) may be preserved when passing through nanoscale holes. The quantum computing nexus is the preservation of quantum information when passing through these waveguides. The waveguides are envisioned as quantum computing devices fundamental to a quantum computer. Decoherence and disentanglement of the photons, being major challenges to bringing quantum computers to fruition, may be reduced or eliminated via their method. Reference is found here at APS physics…

The Purcell Effect: Key to Quantum Repeater. Placing an atom of rubidium between two mirrors could be the key to a reliable quantum repeater. The reliable quantum repeater is a much sought after device as it will enable passing quantum information along a quantum network. The Purcell Effect reveals itself when the atom, between two mirrors, is struck by a laser. Generated by this laser strike is a photon which prefers to launch toward one of the mirrors. Key here are the mirrors, for they attract the atom which otherwise would fly in any direction. This attraction to the mirrors occurs due to the Purcell Effect. With it, the photons can be guided along the mirrored path with partial glass fiber. Passing the photonic energy into another atom permits capture of the quantum information. Strike this next atom with a laser, the photon released retains the quantum information passed to it; and so on. Quite a feat accomplished by research scientists at the Institute of Applied Physics at the University of Bonn.
First Quantum Key Distribution Network: Boston to D.C.

TUDelft Lays Out Broad Plan for a Quantum Internet. University research at TUDelft, Netherlands, has laid out a broad roadmap for a quantum internet. The plan develops the quantum network around two concepts presently unknown to the current internet: (1) Entanglement’s synchronization capability between distant locations; and, (2) entanglement’s inherent security, considered unbreakable. Engineering, computer science, and physics, all must come into agreement and collaborate closely to enable the increasing functionality of each stage.
As put forth by TUDelft, the six stages toward a quantum computing network, in increasing functionality are:
Stage 1: Trusted repeater development (Ex: Quantum key distribution, or QKD)
Stage 2: Prepare & Measure (Ex: QKD, secure delivery of quantum bits between any two network nodes)
Stage 3: Entanglement generation (Ex: Device independent protocols)
Stage 4: Quantum Memory
Stage 5: Few Qubit Fault Tolerant (Ex: Clock synchronization, distributed quantum computation)
Stage 6: Quantum computing (Ex: Complex chemical modeling; financial market prediction)
“The first true quantum networks, allowing the end-to-end transmission of quantum bits, are expected to be realized in the coming years, heralding the dawn of a large-scale quantum internet.”

Silicon Photonic Chips: Solving Two Challenges for Quantum Computing. Silicon computer chips are the foundation for nearly all computing devices today. From your desktop, to the server room, back into your palm inside your smartphone, and circling Earth in the International Space Station, they’re everywhere. Silicon has a well-established manufacturing base and supply chain. However, Moore’s Law suggests we are at the close of doubling the number of bits we can place and process with silicon. Enter quantum computers – a completely new realm – to exponentially expand the speed and complexity of issues which can be solved.
Researchers from the University of Defence Technology in China and the University of Bristol have been working to build quantum bit hardware into the silicon-chip architecture. Doing so would mean obvious advantages to widespread use. How is this being accomplished? Through photons being sent along waveguides where the photons, quantum bits of light, are encoded with information. Henceforth called qubits – short for “quantum bits.”
Though nascent in the silicon-quantum chip’s development, the chip being researched is capable of basic quantum computing. It’s a starting point. With 200+ components, compatible with the common CMOS processor, it has shown quantum-unique capability in repeated two-qubit quantum information processes. This research shows promise to make quantum computers out of scalable technology, readily manufactured, and available. Therein lies why the entrenched silicon-based computing economy is the focus of many quantum computer endeavors.

Qrypt and ORNL: Making a Hybrid Quantum Approach. Though previously reported, Qrypt is again in the news with its hybrid approach to cybersecurity. Having signed an agreement with Oak Ridge National Laboratory to utilize their research and hardware developed for quantum random number generation, the company intends to wed the quantum physics hardware with software incorporating post-quantum computing algorithms. The truly random numbers generated with the hardware, a photon generator, will enable random encryption keys. These are the essence of the fail-safe cryptographic method. Such a hybrid is one of the first of its kind utilizing quantum physics to encrypt data on classical computer systems.

Essential Building Block for Next Gen QC: Basic Reading & Writing. A quantum gate between photons and atoms [photonic qubits and atomic qubits] has successfully transferred information from single photons to atoms. Israel’s Weizmann Institute of Science has taken up the challenge of detecting the single photon’s weak energy and its detectability with ‘material qubits’. The ability to detect and transfer the photonic energy is key to transferring information (bits) between these differing types of qubits. In accomplishing this transfer of information, it is envisioned the method will enable scalable quantum computers and quantum computing networks.
