The University of New Mexico announced recently its new Quantum Photonics and Quantum Technology (QPAQT) graduate program, made possible by a $3 million grant from the National Science Foundation (NSF). Named NRT-QL: Quantum Photonics Interdisciplinary...
Entanglement is a distinguishing feature of quantum many-body systems, and uncovering the entanglement structure for large particle numbers in quantum simulation experiments is a fundamental challenge in quantum information science1. Here we perform experimental investigations of entanglement on the basis of the entanglement Hamiltonian (EH)2 as an effective description of the reduced density operator for large subsystems. We prepare ground and excited states of a one-dimensional XXZ Heisenberg chain on a 51-ion programmable quantum simulator3 and perform sample-efficient ‘learn...

If you have been paying attention to quantum computers, you’ll know they are creeping closer. But are we ready?
If they only had more time Timekeeping quality in circuit-based quantum computations are limited by the achievable circuit complexity, according to a...
