Imaginary time evolution with quantum nondemolition measurements: multi-qubit interactions via measurement nonlinearities

Manikandan Kondappan, Manish Chaudhary, Ebubechukwu O. Ilo-Okeke +2

We show that quantum nondemolition (QND) measurements can be used to realize measurement-based imaginary time evolution. In our proposed scheme, repeated weak QND measurements are…

Hybrid approximation approach to generation of atomic squeezing with quantum nondemolition measurements

Ebubechukwu O. Ilo-Okeke, Manikandan Kondappan, Ping Chen +3

We analyze a scheme that uses quantum nondemolition measurements to induce squeezing of a spinor Bose-Einstein condensate in a double well trap. In a previous paper [Ilo-Okeke et a…

Deterministic preparation of supersinglets with collective spin projections

Ebubechukwu O. Ilo-Okeke, Yangxu Ji, Ping Chen +5

We introduce a procedure to generate supersinglets, the multipartite generalization of angular momentum singlet states. A supersinglet is defined as a total spin zero state consist…

Measurement-based deterministic imaginary time evolution

Yuping Mao, Manish Chaudhary, Manikandan Kondappan +4

We introduce a method to perform imaginary time evolution in a controllable quantum system using measurements and conditional unitary operations. By performing a sequence of weak m…

Stroboscopic quantum nondemolition measurements for enhanced entanglement generation between atomic ensembles

Manish Chaudhary, Yuping Mao, Manikandan Kondappan +3

We develop a measurement operator formalism to handle quantum nondemolition (QND) measurement induced entanglement generation between two atomic gases. We first derive how the QND…

Decoherence effects in quantum nondemolition measurement induced entanglement between Bose-Einstein condensates

Shuai Gao, Ebubechukwu O. Ilo-Okeke, Yuping Mao +4

We study the robustness of quantum nondemolition (QND) measurement-induced entanglement between Bose-Einstein Condensates (BECs). We consider an experimental scheme where two BECs…

Two-axis two-spin squeezed states

Jonas Kitzinger, Manish Chaudhary, Manikandan Kondappan +2

The states generated by the two-spin generalization of the two-axis countertwisting Hamiltonian are examined. We analyze the behavior at both short and long timescales, by calculat…
