Toward Quantum Computation of Quantum Field Theories
October 7, 2021 | Yuta Kikuchi, Brookhaven National Lab
C2QA Quantum Thursdays: Classical computations of quantum field theories (QFTs) typically suffer from prohibitively large degrees of freedom that scales exponentially with their system size.

Quantum computing, on the other hand, is expected to be capable of accommodating such a large number of degrees of freedom, as well as, efficiently carrying out computations by exploiting quantum nature of devices such as superposition of states and quantum entanglement.
