Electro-optic conversion of itinerant Fock states
Thomas Werner, Erfan Riyazi, Samarth Hawaldar +10
Superconducting qubits are a leading candidate for utility-scale quantum computing due to their fast gate speeds and steadily decreasing error rates. The requirement for millikelvi…
Impedance-Engineered Josephson Parametric Amplifier with Single-Step Lithography
Lipi Patel, Samarth Hawaldar, Aditya Panikkar +2
We present the experimental demonstration of an impedance-engineered Josephson parametric amplifier (IEJPA) fabricated in a single-step lithography process. Impedance engineering i…
Entangling remote qubits through a two-mode squeezed reservoir
A. Andrés-Juanes, J. AgustÃ, R. Sett +5
The distribution of entanglement across distant qubits is a central challenge for the operation of scalable quantum computers and large-scale quantum networks. Existing approaches…
Parametric Amplification of Spin-Motion Coupling in Three-Dimensional Trapped-Ion Crystals
Samarth Hawaldar, N. Nikhil, Ana Maria Rey +2
Three-dimensional (3D) crystals offer a route to scale up trapped ion systems for quantum sensing and quantum simulation applications. However, engineering coherent spin-motion cou…
On-demand single-microwave-photon source in a superconducting circuit with wideband frequency tunability
Samarth Hawaldar, Siddhi Satish Khaire, Per Delsing +1
In this article, we propose a new method of generating single microwave photons in superconducting circuits. We theoretically show that pure single microwave photons can be generat…
