Active Learning for Calibrating Entangling Gates via Surrogate-Based Optimization
Caleb Walton, Patricia GarcÃa-Caspueñas, Filippo Zacchei +3
The fidelity of a quantum gate is sensitive to small deviations in the physical control parameters. Unfortunately, it is generally difficult to exactly model the implemented Hamilt…
Circuit Folding: Scalable and Graph-Based Circuit Cutting via Modular Structure Exploitation
Shuwen Kan, Yanni Li, Hao Wang +2
Circuit cutting is a promising technique that leverages both quantum and classical computational resources, enabling the practical execution of large quantum circuits on noisy inte…
Crosstalk Insensitive Trapped-Ion Entanglement through Coupling Matrix Engineering
Vikram Kashyap, Caleb Walton, Sara Mouradian
Optical crosstalk due to imperfect addressing in trapped-ion entangling gates generates unwanted non-local entanglement between target ions and their neighbors that is difficult to…
Hardware-aware and Resource-efficient Circuit Packing and Scheduling on Trapped-Ion Quantum Computers
Miguel Palma, Shuwen Kan, Wenqi Wei +4
The rapid expansion of quantum cloud services has led to long job queues due to single-tenant execution models that underutilize hardware resources. Quantum multi-programming (QMP)…
Quantum-Optimal Frequency Estimation of Stochastic AC Fields
Anirban Dey, Sara Mouradian, Cosmo Lupo +1
Resolving frequencies in a time-dependent field is classically limited by the measurement bandwidth. Using tools from quantum metrology and quantum control may overcome this limit,…
The Effect of Trap Design on the Scalability of Trapped-Ion Quantum Technologies
Le Minh Anh Nguyen, Brant Bowers, Sara Mouradian
To increase the power of a trapped ion quantum information processor, the qubit number, gate speed, and gate fidelity must all increase. All three of these parameters are influence…
