Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Spatially parallel decoding for multi-qubit lattice surgery
Sophia Fuhui Lin, Eric C. Peterson, Krishanu Sankar +1
Running quantum algorithms protected by quantum error correction requires a real time, classical decoder. To prevent the accumulation of a backlog, this decoder must process syndro…
Techniques for combining fast local decoders with global decoders under circuit-level noise
Christopher Chamberland, Luis Goncalves, Prasahnt Sivarajah +2
Implementing algorithms on a fault-tolerant quantum computer will require fast decoding throughput and latency times to prevent an exponential increase in buffer times between the…
OpenQASM 3: A broader and deeper quantum assembly language
Andrew W. Cross, Ali Javadi-Abhari, Thomas Alexander +8
Quantum assembly languages are machine-independent languages that traditionally describe quantum computation in the circuit model. Open quantum assembly language (OpenQASM 2) was p…
Assessing the Influence of Broadband Instrumentation Noise on Parametrically Modulated Superconducting Qubits
E. Schuyler Fried, Prasahnt Sivarajah, Nicolas Didier +4
With superconducting transmon qubits --- a promising platform for quantum information processing --- two-qubit gates can be performed using AC signals to modulate a tunable transmo…
Demonstration of a Parametrically-Activated Entangling Gate Protected from Flux Noise
Sabrina S. Hong, Alexander T. Papageorge, Prasahnt Sivarajah +7
In state-of-the-art quantum computing platforms, including superconducting qubits and trapped ions, imperfections in the 2-qubit entangling gates are the dominant contributions of…
Terahertz generation by beamlet superposition
Koustuban Ravi, Benjamin Ofori-Okai, Keith A. Nelson +1
We analytically show how a superposition of beamlets produces terahertz radiation with greater spatial homogeneity and efficiency compared to tilted-pulse-fronts generated by diffr…
Unsupervised Machine Learning on a Hybrid Quantum Computer
J. S. Otterbach, R. Manenti, N. Alidoust +27
Machine learning techniques have led to broad adoption of a statistical model of computing. The statistical distributions natively available on quantum processors are a superset of…
THz-frequency cavity magnon-phonon-polaritons in the strong coupling regime
Prasahnt Sivarajah, Andreas Steinbacher, Blake Dastrup +1
We demonstrate the strong coupling of both magnons and phonons to terahertz (THz) frequency electromagnetic (EM) waves confined to a photonic crystal (PhC) cavity. Our cavity consi…
Terahertz-frequency magnon-phonon-polaritons in the strong coupling regime
Prasahnt Sivarajah, Jian Lu, Maolin Xiang +4
Strong coupling between light and matter occurs when the two interact strongly enough to form new hybrid modes called polaritons. Here we report on the strong coupling of both the…
THz generation using a reflective stair-step echelon
Benjamin K. Ofori-Okai, Prasahnt Sivarajah, W. Ronny Huang +1
We present a novel method for THz generation in lithium niobate using a reflective stair-step echelon structure. The echelon produces a discretely tilted pulse front with less angu…
