Relativistic zero-knowledge protocol for NP over the internet unconditionally secure against quantum adversaries
André Chailloux, Yann Barsamian
Relativistic cryptography is a proposal for achieving unconditional security that exploits the fact that no information carrier can travel faster than the speed of light. It is bas…
Quantum reference frames for an indefinite metric
Anne-Catherine de la Hamette, Viktoria Kabel, Esteban Castro-Ruiz +1
The current theories of quantum physics and general relativity on their own do not allow us to study situations in which the gravitational source is quantum. Here, we propose a str…
Combined Dissipative and Hamiltonian Confinement of Cat Qubits
Ronan Gautier, Alain Sarlette, Mazyar Mirrahimi
Quantum error correction with biased-noise qubits can drastically reduce the hardware overhead for universal and fault-tolerant quantum computation. Cat qubits are a promising real…
Entropy decay for Davies semigroups of a one dimensional quantum lattice
Ivan Bardet, Ángela Capel, Li Gao +3
Given a finite-range, translation-invariant commuting system Hamiltonians on a spin chain, we show that the Davies semigroup describing the reduced dynamics resulting from the join…
Receiver-Device-Independent Quantum Key Distribution Protocols
Marie Ioannou, Pavel Sekatski, Alastair A. Abbott +3
We discuss quantum key distribution protocols and their security analysis, considering a receiver-device-independent (RDI) model. The sender's (Alice's) device is partially charact…
Lie algebra for rotational subsystems of a driven asymmetric top
Eugenio Pozzoli, Monika Leibscher, Mario Sigalotti +2
We present an analytical approach to construct the Lie algebra of finite-dimensional subsystems of the driven asymmetric top rotor. Each rotational level is degenerate due to the i…
