Resources needed for non-unitary quantum operations

Raam Uzdin

Non-unitary operations generated by an effective non-Hermitian Hamiltonian can be used to create quantum state manipulations which are impossible in Hermitian quantum mechanics. Th…

Continuous intracavity monitoring of the dynamical Casimir effect

A. V. Dodonov

Dynamical Casimir effect (DCE) is the name assigned to the process of generating quanta from vacuum due to an accelerated motion of macroscopic neutral bodies (mirrors) or time-mod…

A third-order exceptional point effect on the dynamics of a single particle in a time-dependent harmonic trap

Raam Uzdin, Emanuele Dalla Torre, Ronnie Kosloff +1

The time evolution of a single particle in a harmonic trap with time dependent frequency omega(t) is well studied. Nevertheless here we show that, when the harmonic trap is opened…

Solid-state electronic spin coherence time approaching one second

Nir Bar-Gill, Linh M. Pham, Andrejs Jarmola +2

Solid-state electronic spin systems such as nitrogen-vacancy (NV) color centers in diamond are promising for applications of quantum information, sensing, and metrology. However, a…

Quantum back-action in spinor condensate magnetometry

S. K. Steinke, S. Singh, P. Meystre +2

We provide a theoretical treatment of the quantum backaction of Larmor frequency measurements on a spinor Bose-Einstein condensate by an off-resonant light field. Two main results…

Collectively Enhanced Interactions in Solid-state Spin Qubits

Hendrik Weimer, Norman Y. Yao, Mikhail D. Lukin

We propose and analyze a technique to collectively enhance interactions between solid-state quantum registers composed from random networks of spin qubits. In such systems, disorde…

Influence of monolayer contamination on electric-field-noise heating in ion traps

A. Safavi-Naini, E. Kim, P. F. Weck +2

Electric field noise is a hinderance to the assembly of large scale quantum computers based on entangled trapped ions. Apart from ubiquitous technical noise sources, experimental s…

Quantum-classical transition of correlations of two coupled cavities

Tony E. Lee, M. C. Cross

We study the difference between quantum and classical behavior in a pair of nonidentical cavities with second-harmonic generation. In the classical limit, each cavity has a limit-c…

Optically mediated nonlinear quantum optomechanics

H. Seok, L. F. Buchmann, S. Singh +1

We consider theoretically the optomechanical interaction of several mechanical modes with a single quantized cavity field mode for linear and quadratic coupling. We focus specifica…
