Multi-time quantum process tomography on a superconducting qubit
Christina Giarmatzi, Tyler Jones, Alexei Gilchrist +3
Current quantum technologies are at the cusp of becoming useful, but still face formidable obstacles such as noise. Noise severely limits the ability to scale quantum devices to th…
Reassessing thermodynamic advantage from indefinite causal order
Matheus Capela, Harshit Verma, Fabio Costa +1
Indefinite causal order is a key feature involved in the study of quantum higher order transformations. Recently, intense research has been focused on possible advantages related t…
Mass-energy equivalence in gravitationally bound quantum states of the neutron
Germain Tobar, Simon Haine, Fabio Costa +1
Gravitationally bound neutrons have become an important tool in the experimental searches for new physics, such as modifications to Newton's force or candidates for dark matter par…
Billiard-ball paradox for a quantum wave packet
Lachlan G. Bishop, Timothy C. Ralph, Fabio Costa
Past studies of the billiard-ball paradox, a problem involving an object that travels back in time along a closed timelike curve (CTC), typically concern themselves with entirely c…
Indefinite temporal order without gravity
Kacper Dębski, Magdalena Zych, Fabio Costa +1
According to the general theory of relativity, time can flow at different rates depending on the configuration of massive objects, affecting the temporal order of events. Recent re…
Operational models of temperature superpositions
Carolyn E. Wood, Harshit Verma, Fabio Costa +1
A quantum system and a thermal bath can reach thermal equilibrium through an interaction, whereupon the system acquires the same temperature as the bath. But how does a delocalised…
