Quantum 5, 429 (2021). https://doi.org/10.22331/q-2021-04-08-429 A central tenet of theoretical cryptography is the study of the minimal assumptions required to implement a given cryptographic primitive. One such primitive is the one-time memory (OTM), introduced by […]
Quantum 5, 428 (2021). https://doi.org/10.22331/q-2021-04-08-428 In this paper we discuss Grover Adaptive Search (GAS) for Constrained Polynomial Binary Optimization (CPBO) problems, and in particular, Quadratic Unconstrained Binary Optimization (QUBO) problems, as a special case. GAS […]
Quantum 5, 427 (2021). https://doi.org/10.22331/q-2021-04-08-427 We present a quantum interior-point method (IPM) for second-order cone programming (SOCP) that runs in time $widetilde{O} left( nsqrt{r} frac{zeta kappa}{delta^2} log left(1/epsilonright) right)$ where $r$ is the rank and […]
The University of Chicago’s Polsky Center for Entrepreneurship and Innovation and the Chicago Quantum Exchange today announced the launch of Duality, the first accelerator program in the nation that is exclusively dedicated to startup companies focused on quantum science and technology—a […]
Quantum 5, 426 (2021). https://doi.org/10.22331/q-2021-04-08-426 We propose an efficient quantum algorithm for simulating the dynamics of general Hamiltonian systems. Our technique is based on a power series expansion of the time-evolution operator in its off-diagonal […]
Duality is a startup accelerator designed to bridge the gap from laboratory to the marketplace. They will offer 12 month programs to selected teams within each yearly cohort that provides entrepreneurial training, business expertise and […]
A team of researchers led by Oak Ridge National Laboratory microscopist Miaofang Chi and Vanderbilt theoretical physicist Sokrates Pantelides has used a new Scanning Transmission Electron Microscope technique to image the electron distribution in ionic […]
Today, the Muon g-2 Collaboration finally published the highly anticipated first result from its measurement of the anomalous magnetic moment of the muon, a precision quantity that offers physicists one of the most promising means […]

A new estimation of the strength of the magnetic field around the muon — a sub-atomic particle similar to, but heavier than, an electron — closes the gap between theory and experimental measurements, bringing it […]
