  • Toward Quantum Computation of Quantum Field Theories

    October 7, 2021

    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. Although the Monte Carlo method is a well-established approach to circumvent the issue in many cases, real-time evolution of physical systems, quantum chromodynamics (QCD) at finite chemical potential, and so on, are notable examples that the Monte Carlo method fails to simulate. 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.
