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…
Path-Independent Quantum Gates with Noisy Ancilla
Wen-Long Ma, Mengzhen Zhang, Yat Wong +5
Ancilla systems are often indispensable to universal control of a nearly isolated quantum system. However, ancilla systems are typically more vulnerable to environmental noise, whi…
High-fidelity measurement of qubits encoded in multilevel superconducting circuits
Salvatore S. Elder, Christopher S. Wang, Philip Reinhold +7
Qubit measurements are central to quantum information processing. In the field of superconducting qubits, standard readout techniques are not only limited by the signal-to-noise ra…
Error-corrected gates on an encoded qubit
Philip Reinhold, Serge Rosenblum, Wen-Long Ma +3
To solve classically hard problems, quantum computers need to be resilient to the influence of noise and decoherence. In such a fault-tolerant quantum computer, noise-induced error…
Quantum error correction of a qubit encoded in grid states of an oscillator
P. Campagne-Ibarcq, A. Eickbusch, S. Touzard +10
Quantum bits are more robust to noise when they are encoded non-locally. In such an encoding, errors affecting the underlying physical system can then be detected and corrected bef…
To catch and reverse a quantum jump mid-flight
Z. K. Minev, S. O. Mundhada, S. Shankar +6
Quantum physics was invented to account for two fundamental features of measurement results -- their discreetness and randomness. Emblematic of these features is Bohr's idea of qua…
Fault-tolerant detection of a quantum error
S. Rosenblum, P. Reinhold, M. Mirrahimi +3
A critical component of any quantum error-correcting scheme is detection of errors by using an ancilla system. However, errors occurring in the ancilla can propagate onto the logic…
Deterministic teleportation of a quantum gate between two logical qubits
K. S. Chou, J. Z. Blumoff, C. S. Wang +7
A quantum computer has the potential to effciently solve problems that are intractable for classical computers. Constructing a large-scale quantum processor, however, is challengin…
Deterministic remote entanglement of superconducting circuits through microwave two-photon transitions
P. Campagne-Ibarcq, E. Zalys-Geller, A. Narla +8
Large-scale quantum information processing networks will most probably require the entanglement of distant systems that do not interact directly. This can be done by performing ent…
On-demand quantum state transfer and entanglement between remote microwave cavity memories
Christopher Axline, Luke Burkhart, Wolfgang Pfaff +9
Modular quantum computing architectures require fast and efficient distribution of quantum information through propagating signals. Here we report rapid, on-demand quantum state tr…
Driving forbidden transitions in the fluxonium artificial atom
U. Vool, A. Kou, W. C. Smith +8
Atomic systems display a rich variety of quantum dynamics due to the different possible symmetries obeyed by the atoms. These symmetries result in selection rules that have been es…
A CNOT gate between multiphoton qubits encoded in two cavities
Serge Rosenblum, Yvonne Y. Gao, Philip Reinhold +8
Entangling gates between qubits are a crucial component for performing algorithms in quantum computers. However, any quantum algorithm must ultimately operate on error-protected lo…
Performance and structure of single-mode bosonic codes
Victor V. Albert, Kyungjoo Noh, Kasper Duivenvoorden +9
The early Gottesman, Kitaev, and Preskill (GKP) proposal for encoding a qubit in an oscillator has recently been followed by cat- and binomial-code proposals. Numerically optimized…
Schrodinger's catapult: Launching multiphoton quantum states from a microwave cavity memory
Wolfgang Pfaff, Christopher J Axline, Luke D Burkhart +6
Encoding quantum states in complex multiphoton fields can overcome loss during signal transmission in a quantum network. Transmitting quantum information encoded in this way requir…
