GKP-inspired high-dimensional superdense coding with energy-time entanglement
Kai-Chi Chang, Arjun Mirani, Murat Can Sarihan +4
Superdense coding, the application of entanglement to boost classical communication capacity, is a cornerstone of quantum communication. In this paper, we propose a high-dimensiona…

Design boosters: from constant-time quantum chaos to -designs and beyond
Soumik Ghosh, Arjun Mirani, Yihui Quek +1
We study a counterintuitive property of 'conditioning' on the result of measuring a subsystem of a quantum state: such conditioning can boost design quality, at the cost of increas…

Learning interacting fermionic Hamiltonians at the Heisenberg limit
Arjun Mirani, Patrick Hayden
Efficiently learning an unknown Hamiltonian given access to its dynamics is a problem of interest for quantum metrology, many-body physics and machine learning. A fundamental quest…
