To capture an image of an object, a photographer typically requires a source of light interacting and scattering away from that object of interest, and a method to detect the light being scattered away from […]
Do you want to know whether a very large integer is a prime number or not? Or if it is a “lucky number”? A new study by SISSA, carried out in collaboration with the University […]
Quantum 7, 913 (2023). https://doi.org/10.22331/q-2023-02-02-913 We present substantially generalized and improved quantum algorithms over prior work for inhomogeneous linear and nonlinear ordinary differential equations (ODE). Specifically, we show how the norm of the matrix exponential […]
Researchers have theorized a new mechanism to generate high-energy “quantum light,” which could be used to investigate new properties of matter at the atomic scale. Click to rate this post! [Total: 0 Average: 0]You have […]
Quantum 7, 912 (2023). https://doi.org/10.22331/q-2023-02-02-912 TensorCircuit is an open source quantum circuit simulator based on tensor network contraction, designed for speed, flexibility and code efficiency. Written purely in Python, and built on top of industry-standard […]
Over 60 years ago, Ralph Fox posed a problem about knots that haunts mathematicians to this day. His question is now often formulated as the “slice-ribbon conjecture,” which posits that two seemingly distinct groups of […]
A team of researchers at the Max Planck Institute of Quantum Optics (MPQ) in Garching has for the first time observed evidence of a phenomenon that had previously only been suspected: a theory predicts that […]
Insider Brief Quantum Computing Inc. announced the appointment of The Honorable James (Jim) Simon, Jr., to establish and lead the company’s technical advisory board. Simon is is a former senior Central Intelligence Agency officer and […]
Quantum 7, 911 (2023). https://doi.org/10.22331/q-2023-02-02-911 The problem of computing the local hidden variable (LHV) value of a Bell inequality plays a central role in the study of quantum nonlocality. In particular, this problem is the […]
Quantum 7, 910 (2023). https://doi.org/10.22331/q-2023-02-02-910 The sign structure of quantum states is closely connected to quantum phases of matter, yet detecting such fine-grained properties of amplitudes is subtle. Here we employ as a diagnostic measurement-induced […]
