Online Colloquium: The art of superposition and entanglement in noisy intermediate-scale quantum (NISQ) era

ABSTRACT

As we have come into the second wave of the quantum revolution, the available quantum hardware is often noisy and with no explicit error correction scheme. Quantum computing tasks using such devices are known as NISQ algorithms [1]. Here, in this talk, I will tell you our recent effort in resource-efficient bosonic quantum simulation [2] given a limited number of qubits and gates, in particular, in the area of quantum simulations of quantum processors [3, 4], and adaptive ansatz construction [5]. Lastly, I will end the talk by briefly outlining our recent work on unsupervised classical machine learning quantum trajectories [6], and how one can make use of our proposal to help build better NISQ devices.
