July 27, 2022 Physicists are claiming significant progress in using quantum computers to study and predict how the state of a large number of interacting quantum particles evolves over time. This was done by ...
Aug. 19, 2021 Researchers have devised a method for measuring the high-spin state of up to four electrons confined on a tiny gallium arsenide quantum dot. This research may lead to quantum computers that can ...
Nov. 17, 2022 Researchers have created grids of tiny clumps of atoms known as quantum dots and studied what happens when electrons dive into these archipelagos of atomic islands. Measuring the behavior of ...
Dec. 5, 2022 Researchers have successfully extended the quantum phase difference estimation algorithm, a general quantum algorithm for the direct calculations of energy gaps, to enable the direct calculation of ...
June 24, 2021 Researchers have developed a method to make previously hardly accessible properties in quantum systems measurable. The new method for determining the quantum state in quantum simulators reduces the ...
Apr. 13, 2021 An international team of physicists has identified a new technique for testing the quality of quantum correlations. Quantum computers run their algorithms on large quantum systems by creating quantum ...
July 21, 2022 For decades computers have been synonymous with binary information -- zeros and ones. Now a team has realized a quantum computer that breaks out of this paradigm and unlocks additional computational ...
Nov. 22, 2022 Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, ...
Nov. 16, 2021 Physicists have created a theory describing how non-reciprocity can be induced at the quantum level, paving the way for non-reciprocal transport in the next generation of ...
Sep. 5, 2023 Researchers have mathematically derived the fundamental limit of heat current flowing into a quantum system comprising numerous quantum mechanical particles in relation to the particle count. ...
