Simple determination of dark states in a general multi-level system
Kaixuan Zhou, June Wu, Junheng Shi +1
In a multi-level energy system with energy transitions, dark states are eigenstates of a Hamiltonian that consist entirely of ground states, with zero amplitude in the excited 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…
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…
Quantum supremacy with spin squeezed atomic ensembles
Yueheng Shi, Junheng Shi, Tim Byrnes
We propose a method to achieve quantum supremacy using ensembles of qubits, using only spin squeezing, basis rotations, and Fock state measurements. Each ensemble is assumed to be…
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…
Ising machines as hardware solvers of combinatorial optimization problems
Naeimeh Mohseni, Peter L. McMahon, Tim Byrnes
Ising machines are hardware solvers which aim to find the absolute or approximate ground states of the Ising model. The Ising model is of fundamental computational interest because…
