A practical guide for building superconducting quantum devices
Yvonne Y. Gao, M. Adriaan Rol, Steven Touzard +1
Quantum computing offers a powerful new paradigm of information processing that has the potential to transform a wide range of industries. In the pursuit of the tantalizing promise…
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…
The Kerr-Cat Qubit: Stabilization, Readout, and Gates
Alexander Grimm, Nicholas E. Frattini, Shruti Puri +6
Quantum superpositions of macroscopically distinct classical states, so-called Schrödinger cat states, are a resource for quantum metrology, quantum communication, and quantum comp…
Bias-preserving gates with stabilized cat qubits
Shruti Puri, Lucas St-Jean, Jonathan A. Gross +9
The code capacity threshold for error correction using qubits which exhibit asymmetric or biased noise channels is known to be much higher than with qubits without such structured…
Gated conditional displacement readout of superconducting qubits
S. Touzard, A. Kou, N. E. Frattini +6
We have realized a new interaction between superconducting qubits and a readout cavity that results in the displacement of a coherent state in the cavity, conditioned on the state…
Pair-cat codes: autonomous error-correction with low-order nonlinearity
Victor V. Albert, Shantanu O. Mundhada, Alexander Grimm +3
We introduce a driven-dissipative two-mode bosonic system whose reservoir causes simultaneous loss of two photons in each mode and whose steady states are superpositions of pair-co…
Confining the state of light to a quantum manifold by engineered two-photon loss
Zaki Leghtas, Steven Touzard, Ioan M. Pop +12
Physical systems usually exhibit quantum behavior, such as superpositions and entanglement, only when they are sufficiently decoupled from a lossy environment. Paradoxically, a spe…
Dynamically protected cat-qubits: a new paradigm for universal quantum computation
Mazyar Mirrahimi, Zaki Leghtas, Victor V. Albert +4
We present a new hardware-efficient paradigm for universal quantum computation which is based on encoding, protecting and manipulating quantum information in a quantum harmonic osc…
