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…
