Mohammad Ansari is a theoretical physicist expert in quantum physics. In 2006, he proposed that quantum gravitational effects can be seen on top of Hawking radiation of black hole. [1] He was the first winner of the John Brodie prize from the Perimeter Institute for Theoretical Physics. [2]

In 2015, Ansari and Nazarov proposed a quantum version of the fluctuation-dissipation theorem in quantum heat engines that is an exact correspondence between Rényi entropy and Full Counting Statistics (FCS) of energy transfers. [3]

Ansari has recently reported a novel symmetry in quantum computation that helps to liberate quantum bits from fundamental parasitic interactions. In 2020, experimenters from IBM Watson Research Center verified the symmetry and eliminated the redundant interactions between qubits. [4]
