UCL research shows that pseudorandom circuits, recently implemented in Google’s ‘quantum supremacy’ experiment, can be used to simulate properties of quantum systems that are hard to compute classically. UCL researchers also think that this randomness […]
QC Ware has added API’s to perform linear algebra library modules to their Forge software. These routines include matrix multiplication and distance estimation and can be used with the data loader library module that we […]

University of Innsbruck 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 number of necessary measurements […]
Nathan Seiberg, 64, still does a lot of the electrical work and even some of the plumbing around his house in Princeton, New Jersey. It’s an interest he developed as a kid growing up in […]
Quantum 5, 482 (2021). https://doi.org/10.22331/q-2021-06-24-482 The new bound on quantum speed limit (in terms of relative purity) is derived by applying the original Mandelstam-Tamm one to the evolution in the space of Hilbert-Schmidt operators acting […]
A framework of statistical physics can be extended to the nonequilibrium setting to discover previously unidentified phases of matter catalyzed by periodic driving. Scientists aim to reduce the runaway heating associated with driving a strongly […]
Quantum 5, 481 (2021). https://doi.org/10.22331/q-2021-06-24-481 Inspired by recent progress in quantum algorithms for ordinary and partial differential equations, we study quantum algorithms for stochastic differential equations (SDEs). Firstly we provide a quantum algorithm that gives […]
Quantum 5, 480 (2021). https://doi.org/10.22331/q-2021-06-24-480 Quantum resource theory under different classes of quantum operations advances multiperspective understandings of inherent quantum-mechanical properties, such as quantum coherence and quantum entanglement. We establish hierarchies of different operations for […]
Using only a pen and paper, a theoretical physicist has proved a decades-old claim that a strong force called Quantum Chromo Dynamics (QCD) leads to light-weight pions, reports a new study published on June 23 […]
