An operational continuum limit of quantum combs
Clara Wassner, Jonáš Fuksa, Jens Eisert +1
Quantum combs are powerful conceptual tools for capturing multi-time processes in quantum information theory, constituting the most general quantum mechanical process. But, despite…
On the complex zeros of the wavefunction
Sacha Cerf, Clara Wassner, Jack Davis +2
The Schrödinger wavefunction is ubiquitous in quantum mechanics, quantum chemistry, and bosonic quantum information theory. Its zero-set for fermionic systems is well-studied and c…
Detecting quantum non-Gaussianity with a single quadrature
Clara Wassner, Jack Davis, Sacha Cerf +2
Full reconstruction of quantum states from measurement samples is often a prohibitively complex task, both in terms of the experimental setup and the scaling of the sample size wit…
Holonomic quantum computation: a scalable adiabatic architecture
Clara Wassner, Tommaso Guaita, Jens Eisert +1
Holonomic quantum computation exploits the geometric evolution of eigenspaces of a degenerate Hamiltonian to implement unitary evolution of computational states. In this work we in…
