Next-generation superconducting qubits for quantum computing

February 1, 2023 by | Uncategorized

Abstract: The world of superconducting qubits has been dominated by the transmon for a while. Over the course of more than a decade, much effort has been devoted to enhancing this circuit’s coherence times. Despite the remarkable success, we should ask: is the transmon the best we can do, and will it ultimately suffice for

Hypertwined Quantum Field Theory

February 1, 2023 by | Uncategorized

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

101 Fun Things to Do with a Quantum Entanglement Source

February 1, 2023 by | Uncategorized

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

Demonstration of algorithmic quantum speedup

February 1, 2023 by | Uncategorized

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

Many-body quantum vacuum fluctuation engines

February 1, 2023 by | Uncategorized

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

Multilayer Graphene as an Endoreversible Otto Engine

February 1, 2023 by | Uncategorized

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
