Understanding the effects of the COVID-19 pandemic on the population means knowing more than just the total number of infections and deaths. As with many diseases, after the acute infection has passed, a constellation of […]
Quantum 5, 491 (2021). https://doi.org/10.22331/q-2021-07-01-491 The quantum approximate optimization algorithm (QAOA) is a prospective near-term quantum algorithm due to its modest circuit depth and promising benchmarks. However, an external parameter optimization required in QAOA could […]
This may be one small step for quantum experimentation, but IBM scientists claim that a recent experiment offers a giant leap in demonstrating how quantum computers can best classical devices at certain tasks. Quantum computing, […]
Quantum 5, 490 (2021). https://doi.org/10.22331/q-2021-07-01-490 We propose a parameter estimation protocol for generalized Pauli channels acting on $d$-dimensional Hilbert space. The salient features of the proposed method include product probe states and measurements, the number […]
Quantum 5, 489 (2021). https://doi.org/10.22331/q-2021-07-01-489 We show that the quantum Fisher information attained in an adiabatic approach to critical quantum metrology cannot lead to the Heisenberg limit of precision and therefore $regular$ quantum metrology under […]
Physicists at Technische Universität Kaiserslautern in the team of Professor Dr. Herwig Ott have succeeded for the first time in directly observing collisions between highly excited atoms, so-called Rydberg atoms, and atoms in the ground […]
