Abstract: Hypertwined analysis is a refinement of general hypercomplex theories of differential operators. In the assumption that the configuration space has a hypertwined structure, I will discuss several (re)interpretations of notions and results in Topological Quantum Field Theory (TQFT), such as supersymmetry, path–integral quantization, cancellation of anomalies, et al. Particular TQFTs of interest in this
Abstract: The Quantum Information Revolution is in full swing, and entanglement — the spooky nonclassical, nonlocal connection that can be shared by quantum particles — is the key ingredient. In this talk we’ll discuss how to create (photon) entanglement, and several applications for secure communication and quantum-enhanced sensing. Time permitting, we’ll include a lesson in
Abstract: Superconducting materials are known to be good thermal insulators at sufficiently low temperatures thanks to the presence of the energy gap in their density of states (DOS). Yet, the proximity effect allows to tune the local DOS of a metallic wire by controlling the phase biasing imposed across it. As a result, the wire
Abstract: Despite the development of increasingly capable quantum computers, an experimental demonstration of a provable algorithmic quantum speedup employing today’s non-fault-tolerant devices has remained elusive. In this talk, I will report on the first demonstration of such a speedup, quantified in terms of the scaling of time-to-solution with problem size. The demonstration is based on
Abstract: Owing to their wave-like nature, quantum systems can never be truly at rest. Indeed, the value of some observables—those which do not commute with the Hamiltonian—fluctuate, even when the system is in its ground state. Following major advances in the manipulation and control of quantum systems, the prospect of extracting useful work out of these
Abstract: Graphene is perhaps the most prominent “Dirac material,” a class of systems whose lattice structure gives rise to charge carriers that behave as relativistic massless fermions. This emergence of relativistic behavior at laboratory scale energies makes graphene an ideal environment for probing the thermodynamics of relativistic quantum systems. For multilayer graphene, consisting of several
