Optimal Quantum Transfer from Input Flying Qubit to Lossy Quantum Memory
Eric Chatterjee, Daniel Soh, Matt Eichenfield
In a quantum network, a key challenge is to minimize the direct reflection of flying qubits as they couple to stationary, resonator-based memory qubits, as the reflected amplitude…
Ab-Initio Calculations of Nonlinear Susceptibility and Multi-Phonon Mixing Processes in a 2DEG-Piezoelectric Heterostructure
Eric Chatterjee, Alexander Wendt, Daniel Soh +1
Solid-state elastic-wave phonons are a promising platform for a wide range of quantum information applications. An outstanding challenge and enabling capability in harnessing phono…
Computational Superiority of Non-Markovian Kerr Feedback in Continuous-Variable Quantum Reservoir Computing
Daniel Soh
A linear optical medium can delay, mix, and superpose light, but never make two pulses multiply: multiplication is nonlinear, and a linear system has no such operation. This roots…
Optical Gottesman-Kitaev-Preskill qubit generation via approximate squeezed coherent state superposition breeding
Andrew J. Pizzimenti, Daniel Soh
Gottesman-Kitaev-Preskill (GKP) qubits, known for their exceptional error-correction capabilities, are highly coveted in quantum computing. However, generating optical GKP qubits h…
Microwave response in a topological superconducting quantum interference device
Wei Pan, Daniel Soh, Wenlong Yu +2
Photon detection at microwave frequency is of great interest due to its application in quantum computation information science and technology. Herein are results from studying micr…
Quantum-Limited Acoustoelectric Amplification in a Piezoelectric-2DEG Heterostructure
Eric Chatterjee, Daniel Soh, Matt Eichenfield
We provide a quantum mechanical description of phonon amplification in a heterostructure consisting of a two-dimensional electron gas (2DEG) stacked on top of a piezoelectric mater…
