Holding the Universe Together with Quantum Computing Simulation
Holding the Universe Together with Quantum Computing Simulation A group of scientists at the Department of Energy’s Fermilab has figured out how to use quantum computing to simulate the fundamental interactions that hold together our universe. In a paper published in Physical Review Letters, Fermilab researchers fill a conspicuous gap in modeling the subatomic world […]
Passive Measurement-Device-Independent Quantum Key Distribution
Efficient Passive Measurement-Device-Independent Quantum Key Distribution Author(s): Chun-Hui Zhang, Chun-Mei Zhang, and Qin Wang To date, only active-decoy-state methods have been adopted in current measurement-device-independent (MDI) quantum key distribution (QKD) protocols, causing security loopholes when modulating multiple light intensities with practical devices. To solve this problem, the passive-decoy-state method will be a good choice. Until […]
Quantum Bayesianism; Putting the Scientist Back in Science
Quantum Bayesianism; Putting the Scientist Back in Science Considering the ongoing challenge of taking measurements in the quantum world and the meaning and accuracy of those measurements, do they form a true picture? Some say not. Objectivity and subjectivity come into the equation. Not to be left out is the philosophical view. Qubit. Excerpts and […]
A Step Towards Probabilistic Computing
A Step Towards Probabilistic Computing When it comes to performing a calculation destined to arrive at an exact result, humans are hopelessly inferior to the computer. In other areas, humans are still lengths ahead of it: An example is signal processing, which plays an important role in autonomous driving. In the search for new computer […]
Proposed: The China Technology Transfer Control Act of 2019
Proposed: The China Technology Transfer Control Act of 2019. The U.S. Senate has introduced a new bill aimed at thwarting China’s intellectual property theft. The proposed legislation focusses on disruptive technologies. This includes quantum computing. Qubit. Excerpts and salient points ~ • The China Technology Transfer Control Act of 2019… would place a large swath […]
Heidelberg Researchers investigate “error bound” that limits usable simulations
Digital Quantum Simulators Can Be Astonishingly Robust Heidelberg Researchers investigate “error bound” that limits usable simulations. In solving quantum-physical problems in many-body systems, such as predicting material properties, conventional computers rapidly reach the limits of their capacity. Digital quantum simulators might help, but until now they are drastically limited to small systems with few particles […]
Silicon Based Qubit Calculation Accuracy
Silicon Based Qubit Calculation Accuracy. UNSW, Sydney. Quantum world-first: researchers can now tell how accurate two-qubit calculations in silicon really are. After being the first team to create a two-qubit gate in silicon in 2015, UNSW Sydney engineers are breaking new ground again: they have measured the accuracy of silicon two-qubit operations for the first […]
Oak Ridge National Laboratory Adds Quantum Information Science Home
Oak Ridge National Laboratory Adds Quantum Information Science Home. New research facility will serve ORNL’s growing mission in computing, materials research and development. Energy Secretary Rick Perry, Congressman Chuck Fleischmann and lab officials today broke ground on a multipurpose research facility that will provide state-of-the-art laboratory space for expanding scientific activities at the Department of […]
Generating high-quality single photons for quantum computing
MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers. Quantum emitters generate photons that can be detected one at a time. Consumer quantum computers and devices could potentially leverage certain properties of those […]
