Quantum Contextuality and Entanglement-Free Grover Search in a Trapped-Ion Optical Qudit
Tarun Dutta, Jasper Phua Sing Cheng, Alex Jin +3
Quantum computational advantage is generally attributed to coherent interference and other non-classical resources, yet their respective roles remain difficult to disentangle in ex…
Pound-Drever-Hall Feedforward for Trapped-Ion Optical Qubits
Jia-Yang Gao, Jianwei Lee, Morteza Ahmadi +1
Laser phase noise is one of the limiting factors that dictate gate fidelities and coherence times in trapped-ion quantum systems. Previous studies have reported that when the Rabi…
Realizing Quantum Adversarial Defense on a Trapped-ion Quantum Processor
Alex Jin, Tarun Dutta, Anh Tu Ngo +2
Classification is a fundamental task in machine learning, typically performed using classical models. Quantum machine learning (QML), however, offers distinct advantages, such as e…
A scalable narrow linewidth high power laser for barium ion optical qubit
Morteza Ahmadi, Tarun Dutta, Manas Mukherjee
The linewidth of a laser plays a pivotal role in ensuring the high fidelity of ion trap quantum processors and optical clocks. As quantum computing endeavors scale up in qubit numb…
Practicality of training a quantum-classical machine in the NISQ era
Tarun Dutta, Alex Jin, Clarence Liu Huihong +2
