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 […]

A Chinese team led by Jian-Wei Pan, often called that country’s Father of Quantum, is reporting that they have achieved another demonstration of quantum supremacy with a superconducting quantum computer, Zuchongzhi. In a study reported […]
In 1934, physicist Eugene Wigner made a theoretical prediction based on quantum mechanics that for 87 years went unseen. Click to rate this post! [Total: 0 Average: 0]You have already voted for this article
We offer a 2-years post-doctoral position (with possible extension) for a motivated experimental researcher to join our work on spin qubits in silicon carbide and diamond. Our goal is to push the limits in controlling […]
In July 1967, at the height of the Cold War, American satellites that had been launched to look for Soviet nuclear weapons tests found something wholly unexpected. The Vela 3 and 4 satellites observed brief […]
In quantum mechanics, entanglement means two or more qubits become a single quantum state, a state which offers vastly more power to probe computational possibilities than in the qubits’ previously separated state when coaxed into […]
