Noise Transfer Approach to GKP Quantum Circuits
Timothy C Ralph, Matthew Winnel, S Nibedita Swain +1
The choice between the Schroedinger and Heisenberg pictures can significantly impact the computational resources needed to solve a problem, even though they are equivalent formulat…
Looping back to the past through free fall in a controlled warp drive spacetime
Achintya Sajeendran, Timothy C. Ralph
We present a modification to a 'rotating' version of the dynamical Alcubierre spacetime, which was previously shown to permit closed timelike curves. We find that if the effective…
Quantum state tomography on closed timelike curves using weak measurements
Lachlan G. Bishop, Fabio Costa, Timothy C. Ralph
Any given prescription of quantum time travel necessarily endows a Hilbert space to the chronology-violating (CV) system on the closed timelike curve (CTC). However, under the two…
Exploiting Spatial Diversity in Earth-to-Satellite Quantum-Classical Communications
Ziqing Wang, Timothy C. Ralph, Ryan Aguinaldo +1
Despite being an integral part of the vision of quantum Internet, Earth-to-satellite (uplink) quantum communications have been considered more challenging than their satellite-to-E…
Quantum-Amplified Simultaneous Quantum-Classical Communications
Nicholas Zaunders, Ziqing Wang, Timothy C. Ralph +2
Classical free-space optical (FSO) communication promises massive data throughput rates relative to traditional wireless technologies - an attractive outcome now being pursued in t…
