Mitigating many-body quantum crosstalk with tensor-network robust control
Nguyen H. Le, Florian Mintert, Eran Ginossar
Quantum crosstalk poses a major challenge to scaling up quantum computations as its strength is typically unknown and its effect accumulates exponentially as system size grows. Her…
Fast thermal state preparation beyond native interactions
Alexander van Lomwel, Paul M. Schindler, Modesto Orozco-Ruiz +3
While questions on quantum simulation of ground state physics are mostly focussed on the realization of effective interactions, most work on quantum simulation of thermal physics e…
Amplitude-noise-resilient entangling gates for trapped ions
Nguyen H. Le, Modesto Orozco-Ruiz, Sahra A. Kulmiya +4
Noise resilience of quantum information processing is a crucial precondition to reach the fault-tolerance threshold. While resilience to many types of noise can be achieved through…
Robust implicit quantum control of interacting spin chains
Luca Stefanescu, Louis Edwards-Pratt, Jeremy O'Connor +3
Robust quantum control can achieve noise-resilience of quantum systems and quantum technological devices. While the need for noise-resilience grows with the number of fluctuating q…
Quantum control without quantum states
Modesto Orozco-Ruiz, Nguyen H. Le, Florian Mintert
We show that combining ideas from the fields of quantum invariants and of optimal control can be used to design optimal quantum control solutions without explicit reference to quan…
