The U.S. Department of Energy’s research teams recently integrated quantum dots and donor atoms to produce qubits with little degradation. There are two primary benefits from this new qubit. First, maintaining of the quantum data stored in the spin (coherence). Second, use of silicon materials which have manufacturing infrastructure readily available. Keeping coherence high is a necessity to developing practical quantum computers.
University of Rochester researchers have published a list of ’12 Herculean tasks’ they believe will inspire the next quantum scientists. One of the authors demonstrated the use of ‘twisted light’ to slightly more than double data-throughput per photon. The approach utilized the mechanics of orbital angular momentum (OAM) of photons for encoding the data. Two of the tasks put forth to ponder are, “What is the future of quantum coherence, squeezing, and entanglement for enhanced super resolution and sensing?”, “How can we solve some of humanity’s biggest problems through new quantum technologies?”
Yale sees quantum science and technology as a “new frontier of fundamental knowledge” about the universe; hopes to expand program to international acclaim.
In May, the European Space Agency (ESA) teamed with Satellite-Enabled Solutions (SES) to develop the Quantum Cryptography Telecommunication System, aka QUARTZ. Last week, SES announced ten partners in the project, each of which will contribute to the quantum key distribution system.
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.
Israeli led researchers at the Weizman Institute of Science have presented evidence for particles capable of storing quantum information — without needing error correction.
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.
Quantum supremacy is a popular term but 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.
Researchers in Japan have theoretically met the challenge of errors caused by noise in qubit production
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?
