Gaussian Boson Sampling (GBS) is a leading model of sub-universal quantum computation realizable with current photonic technologies. Despite recent experimental progress, the validation of GBS devices remains an open problem. In this talk, I present results on the asymptotic behavior of photon-number cumulants of multimode Gaussian states and discuss how these quantities can be used as...

We aim to introduce an operational definition of a clock as a physical system and elucidate what

makes a clock quantum in nature. We proceed by introducing an architectural framework for a
clock, which comprises a driver, an oscillator, a frequency reference, a readout, and a stabilizer. We
then apply our framework to three realizations, namely mechanical, atomic, and... -

We introduce a hybrid quantum-classical neural network whose quantum layer is based on the paradigm of fermionic quantum computing. This model broadens the scope of fermionic machine learning (FermiML) introduced in [arXiv:2404.19032] by extending its applicability to a wider range of learning tasks. Since fermionic quantum circuits are efficiently simulable classically in polynomial time, our...

We propose a unifying framework for characterizing pure and mixed state phases of matter across equilibrium, non equilibrium, and metastable regimes. We introduce the concept of locally stable states, defined by the operational property that any local operation (including post selection) can be reversed by a local channel. We prove that local stability is equivalent to a state being short...

Astrophysical environments provide natural laboratories for collective quantum phenomena on scales far beyond those accessible in conventional laboratory experiments. In this talk, I will discuss how large radiatively coupled ensembles in astrophysical media can develop macroscopic coherence and exhibit cooperative radiative behavior, including superradiant and subradiant dynamics. Using...

The eigenstate thermalization hypothesis formally connects time evolution in a quantum system with the micro-canonical ensemble system average in statistical physics. The formal reliance on random matrix theory is discussed, justifying the main statement, and then extended to the case of quantum circuits where the micro-canonical ensemble emerges explicitly without invoking random matrices....

Abstract: Ontological models of quantum theory seek to realize quantum theory as a statistical theory over underlying degrees of freedom, whose measurement statistics are described by classical probability theory. Harrigan and Spekkens (2010) proposed a distinction between ontological models in which pure quantum states represent states of reality ($\psi$-ontic) or knowledge about reality...
