Efficient quantum simulation of unitary gates based on atomic ensembles
Manish Chaudhary, Tim Byrnes
We develop a technique to perform efficient unitary time evolution of a general spin Hamiltonian based on the system with identical qubits, as naturally realized by permutation sym…
Dynamical phase transition in generalized Dicke model with strongly interacting trapped Rydberg ions
Manish Chaudhary, Rejish Nath, Weibin Li
We study dynamical phase transitions in the generalized dissipative Dicke model in an array of trapped Rydberg ions, where their density-density interactions compete with the colle…
Spin Phonon Relaxation Dynamics from a Conical Intersection of Trapped Rydberg Ions
Manish Chaudhary, Rejish Nath, Weibin Li
Non-adiabatic processes near conical intersections are rooted in the stronger coupling between electronic and nuclear degrees of freedom. Using a system of two trapped Rydberg ions…
Macroscopic quantum teleportation with ensembles of qubits
Manish Chaudhary, Zhiyuan Lin, Shuang Li +4
We develop methods for performing quantum teleportation of the total spin variables of an unknown state, using quantum nondemolition measurements, spin projection measurements, and…
Photon loss effects on light-mediated non-Gaussian entangled Bose-Einstein condensates projecting with different photon measurement outcomes
Shuai Gao, Manish Chaudhary, Alexey N. Pyrkov +6
The theory of quantum information processing for macroscopic qubits is based on the fact that every macroscopic qubit has a conserved number of particles. However, from an experime…
Optical and atomic decoherence in entangled atomic ensembles generated by quantum nondemolition measurements
Shuai Gao, Shuang Li, Manish Chaudhary +4
We study the effects of decoherence in the form of optical phase diffusion, photon loss and gain, and atomic dephasing in entangled atomic ensembles produced via quantum nondemolit…
Macroscopic maximally entangled state preparation between two atomic ensembles
Manish Chaudhary, Ebubechukwu O. Ilo-Okeke, Valentin Ivannikov +1
We develop a scheme to prepare a macroscopic maximally entangled state (MMES) between two atomic ensembles using adaptive quantum nondemolition (QND) measurements. The quantum stat…
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…
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…
Remote state preparation of two-component Bose-Einstein condensates
Manish Chaudhary, Matteo Fadel, Ebubechukwu O. Ilo-Okeke +3
A protocol for remote state preparation is proposed for spin ensembles, where the aim is to prepare a state with a given set of spin expectation values on a remote spin ensemble us…
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…
