Weak continuous measurements require more work than strong ones
Lorena Ballesteros Ferraz, Cyril Elouard
Understanding the energy cost of quantum measurement process and its connection to the measurement performance faces the challenge of modeling the objectification process. The latt…
Exploring weak value arguments and Bargmann invariants in -level quantum systems through the Majorana symmetric representation
Lorena B Ferraz, Dominique L Lambert, Yves Caudano
This work examines the argument of weak values for general observables and develops a geometric description on the Bloch sphere. We apply the Majorana symmetric representation to r…
Revivals and quantum carpets for the relativistic Schrödinger equation
Benoît Zumer, Florent Daem, Alexandre Matzkin
We investigate wavepacket dynamics for a relativistic particle in a box evolving according to the relativistic Schrödinger (also known as the Salpeter) equation. We derive the sol…
Measured dynamics of an XXZ quantum simulator in a highly symmetrical double-ringed geometry
D. J. Papoular
We theoretically identify observable consequences of spatial and spin symmetries on the dynamics of a small XXZ quantum simulator. Our proposed protocol relies on the choice of sui…
The non-stabilizerness of fermionic Gaussian states
Mario Collura, Jacopo De Nardis, Vincenzo Alba +1
We introduce an efficient method to quantify nonstabilizerness in fermionic Gaussian states, overcoming the long-standing challenge posed by their extensive entanglement. Using a p…
Universality in the Anticoncentration of Noisy Quantum Circuits at Finite Depths
Arman Sauliere, Guglielmo Lami, Corentin Boyer +2
We present universal properties of anticoncentration in weakly noisy quantum circuits at finite depth. We develop a generic framework for single- and multi-qubit noise channels in…
