An important problem in quantum computing is the so-called approximate synthesis problem: to find a quantum circuit, preferably as short as possible, that approximates a given unitary operator

The research community has made spectacular progress in building the magical quantum machines, developing new applications, designing security platforms up until the current state where the

The field of quantum information processing (quantum computation and quantum communication) has grown considerably in recent decades. Numerous proof-of-principle experiments on small-scale quantum

If we are ever to understand what computers can collectively do, we need a new theory of complexity. Recent evolutions, including the cloud and the multicore, are turning computing ubiquitously

Much of the technical terminology of computer science betrays its logical heritage: ‘language’, ‘symbol’, ‘syntax’, ‘semantics’, ‘value’, ‘reference’, ‘identifier’, ‘data’, etc.  Classically,

I will show how we can produce exotic representations of surface groups from the Witten-Reshetikhin-Turaev TQFT. These representations have infinite images and give points on character varieties that

Quantum Field Theory and Arithmetic

Out of the quantum product of a projective smooth variety, we can construct a vector bundle with a at connection and a pairing, these data are called quantum D-modules. In a recent paper of
