Clifford-deformed zero-rate LDPC codes with 50% biased noise thresholds
Jagannath Das, Sayandip Dhara, Pedro Medina +2
Applying single-qubit Clifford unitaries to a Pauli stabilizer code produces a Clifford-deformed variant whose stabilizers remain Pauli operators, but with locally rotated Pauli ax…
Satellites promise global-scale quantum networks
Sumit Goswami, Sayandip Dhara, Neil Sinclair +10
Academia, governments, and industry around the world are on a quest to build long-distance quantum communication networks for a future quantum internet. Using air and fiber channel…
Satellite Relayed Global Quantum Communication without Quantum Memory
Sumit Goswami, Sayandip Dhara
Photon loss is the fundamental issue towards the development of quantum communication. We present a proposal to mitigate photon loss even at large distances and hence to create a g…
Atomistic modeling of a superconductor-transition-metal dichalcogenide-superconductor Josephson junction
Jouko Nieminen, Sayandip Dhara, Wei-Chi Chiu +2
Using an atomistic tight-binding model, we study the characteristics of a Josephson junction formed by monolayers of MoS sandwiched between Pb superconducting electrodes. We de…
Logical Majorana zero modes in a nanowire network
Sayandip Dhara, Garry Goldstein, Claudio Chamon +1
We present a scheme to use physical Majorana quasi-zero modes at each junction of a two-dimensional nanowire network to build a logical Majorana zero mode, the location of which is…
Sun CubE OnE: A Multi-wavelength Synoptic Solar Micro Satellite
L. Giovannelli, F. Berrilli, M. Casolino +25
The Sun cubE onE (SEE) is a 12U CubeSat mission proposed for a phase A/B study to the Italian Space Agency that will investigate Gamma and X-ray fluxes and ultraviolet (UV) solar e…
Machine Learning Regression for Operator Dynamics
Justin Reyes, Sayandip Dhara, Eduardo R. Mucciolo
Determining the dynamics of the expectation values for operators acting on a quantum many-body (QMB) system is a challenging task. Matrix product states (MPS) have traditionally be…
Quantum Coherence in Ergodic and Many-Body Localized Systems
Sayandip Dhara, Alioscia Hamma, Eduardo R. Mucciolo
Quantum coherence quantifies the amount of superposition a quantum state can have in a given basis. Since there is a difference in the structure of eigenstates of the ergodic and m…
Selective observation of Goos-Hänchen and Imbert-Federov shifts in partial reflection via optimized weak measurements in linear and elliptical polarization basis
S. Goswami, S. Dhara, M. Pal +3
The spatial and the angular variants of the Goos-Hänchen (GH) and the Imbert-Federov (IF) beam shifts contribute in a complex interrelated way to the resultant beam shift in partia…
