Symmetries of Pauli Noise from Lindbladian Dynamics
Moein Malekakhlagh, Edward H. Chen, Luke C. G. Govia +1
Characterizing noise in quantum circuits is fundamentally limited by gauge degrees of freedom; certain parameters, such as the individual contributions of state preparation and mea…
Single snapshot non-Markovianity of Pauli channels
Alireza Seif, Moein Malekakhlagh, Swarnadeep Majumder +1
Pauli channels are widely used to describe errors in quantum computers, particularly when noise is shaped via Pauli twirling. A common assumption is that such channels admit a Mark…
Distilled remote entanglement between superconducting qubits across optical channels
Nicolas Dirnegger, Moein Malekakhlagh, Vikesh Siddhu +5
A promising quantum computing architecture comprises modules of superconducting quantum processors linked via optical channels using quantum transducers. As quantum transducer hard…
Large-scale Lindblad learning from time-series data
Ewout van den Berg, Brad Mitchell, Ken Xuan Wei +1
In this work, we develop a protocol for learning a time-independent Lindblad model for operations that can be applied repeatedly on a quantum computer. The protocol is highly scala…
Randomized benchmarking of a high-fidelity remote CNOT gate over a meter-scale microwave interconnect
Kentaro Heya, Timothy Phung, Moein Malekakhlagh +8
High-fidelity, meter-scale microwave interconnects between superconducting quantum processor modules are a key technology for extending system size beyond constraints imposed by de…
Efficient Lindblad synthesis for noise model construction
Moein Malekakhlagh, Alireza Seif, Daniel Puzzuoli +2
Effective noise models are essential for analyzing and understanding the dynamics of quantum systems, particularly in applications like quantum error mitigation and correction. How…
