Ancilla-assisted nondestructive discrimination of distributed GHZ-class states
Abdul Q. Batin, Suman Chand, Rajiuddin Sk +1
Nondestructive quantum state discrimination is a fundamental primitive in distributed quantum information processing, where shared multipartite entangled resources need to be ident…
Anisotropy-assisted thermodynamic advantage of a local-spin thermal machine
Chayan Purkait, Suman Chand, Asoka Biswas
We study quantum Otto thermal machines with a two-spin working system coupled by anisotropic interaction. Depending on the choice of different parameters, the quantum Otto cycle ca…
Finite-time performance of a single-ion quantum Otto engine
Suman Chand, Shubhrangshu Dasgupta, Asoka Biswas
We study how a quantum heat engine based on a single trapped ion performs in finite time. The always-on thermal environment acts like the hot bath, while the motional degree of fre…
Critical-point behavior of a measurement-based quantum heat engine
Suman Chand, Asoka Biswas
We study how a quantum heat engine performs across the critical value of an external parameter, pertaining to the quantum phase transition. Considering a two-ion system subjected t…
Measurement-induced operation of two-ion quantum heat machines
Suman Chand, Asoka Biswas
We show how one can implement a quantum heat machine by using two interacting trapped ions, in presence of a thermal bath. The electronic states of the ions act like a working subs…
Single-ion quantum Otto engine with always-on bath interaction
Suman Chand, Asoka Biswas
We demonstrate how a quantum Otto engine (QOE) can be implemented using a single ion and an always-on thermal environment. The internal degree of freedom of the ion is chosen as th…
