Note: Nonuniqueness of generalized quantum master equations for a single observable

Kavli Affiliate: David T. Limmer | First 5 Authors: Nathan Ng, David T. Limmer, Eran Rabani, , | Summary: When deriving exact generalized master equations for the evolution of a reduced set of degrees of freedom, one is free to choose what quantities are relevant by specifying projection operators. However, obtaining a reduced description does […]

Demonstration of universal control between non-interacting qubits using the Quantum Zeno effect

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Eliya Blumenthal, Chen Mor, Asaf A. Diringer, Leigh S. Martin, Philippe Lewalle | Summary: The Zeno effect occurs in quantum systems when a very strong measurement is applied, which can alter the dynamics in non-trivial ways. Despite being dissipative, the dynamics stay coherent within any degenerate […]

Direct evaluation of rare events in active matter from variational path sampling

Kavli Affiliate: David T. Limmer | First 5 Authors: Avishek Das, Benjamin Kuznets-Speck, David T. Limmer, , | Summary: Active matter represents a broad class of systems that evolve far from equilibrium due to the local injection of energy. Like their passive analogues, transformations between distinct metastable states in active matter proceed through rare fluctuations, […]

Tuning color centers at a twisted interface

Kavli Affiliate: Michael Crommie | First 5 Authors: Cong Su, Fang Zhang, Salman Kahn, Brian Shevitski, Jingwei Jiang | Summary: Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Employing cathodoluminescence, we demonstrate that an ultraviolet-emitting single photon emitter can […]
