Open-Source Highly Parallel Electromagnetic Simulations for Superconducting Circuits
David Sommers, Zach Degnan, Divita Gautam +4
Electromagnetic simulations form an indispensable part of the design and optimization process for superconducting quantum devices. Although several commercial platforms exist, open…
Experimental realization of qubit-state-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Chun-Ching Chiu +3
We experimentally realise the theoretical proposal for in-situ tunable photonic edge states emerging from qubits coupled to a waveguide with a photonic bandgap. These edge states a…
Fano-enhanced low-loss on-chip superconducting microwave circulator
N. Pradeep Kumar, Dat Thanh Le, Prasanna Pakkiam +2
Ferrite-free circulators that are passive and readily integratable on a chip are highly sought-after in quantum technologies based on superconducting circuits. In our previous work…
Passive microwave circulation on a superconducting chip
Arkady Fedorov, N. Pradeep Kumar, Dat Thanh Le +3
Building large-scale superconducting quantum circuits will require miniaturisation and integration of supporting devices including microwave circulators, which are currently bulky,…
Multi-time quantum process tomography on a superconducting qubit
Christina Giarmatzi, Tyler Jones, Alexei Gilchrist +3
Current quantum technologies are at the cusp of becoming useful, but still face formidable obstacles such as noise. Noise severely limits the ability to scale quantum devices to th…
Qubit-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Mikhail Pletyukhov +1
We propose an in-situ tunable chiral quantum system, composed of a quantum emitter coupled to a waveguide based on the Rice-Mele model (where we alternate both the on-site potentia…
Double Upconversion for Superconducting Qubit Control realised using Microstrip Filters
Jonathan Dearlove, Prasanna Pakkiam, Arkady Fedorov
Superconducting qubits provide a promising platform for physically realising quantum computers at scale. Such devices require precision control at microwave frequencies. Common pra…
Effect of Measurement Backaction on Quantum Clock Precision Studied with a Superconducting Circuit
Xin He, Prasanna Pakkiam, Adil A. Gangat +3
We theoretically and experimentally study the precision of a quantum clock near zero temperature, explicitly accounting for the effect of continuous measurement. The clock is creat…
Single-shot readout of multiple donor electron spins with a gate-based sensor
Mark R. Hogg, Prasanna Pakkiam, Samuel K. Gorman +5
Proposals for large-scale semiconductor spin-based quantum computers require high-fidelity single-shot qubit readout to perform error correction and read out qubit registers at the…
Neural networks for on-the-fly single-shot state classification
Rohit Navarathna, Tyler Jones, Tina Moghaddam +5
Neural networks have proven to be efficient for a number of practical applications ranging from image recognition to identifying phase transitions in quantum physics models. In thi…
