Nonlinear spectroscopy of superconducting anharmonic resonators
David P. DiVincenzo, John A. Smolin
We formulate a model for the steady state response of a nonlinear quantum oscillator structure, such as those used in a variety of superconducting qubit experiments, when excited b…
Detecting Incapacity
Graeme Smith, John A. Smolin
Using unreliable or noisy components for reliable communication requires error correction. But which noise processes can support information transmission, and which are too destruc…
A simple all-microwave entangling gate for fixed-frequency superconducting qubits
Jerry M. Chow, A. D. Corcoles, Jay M. Gambetta +8
We demonstrate an all-microwave two-qubit gate on superconducting qubits which are fixed in frequency at optimal bias points. The gate requires no additional subcircuitry and is tu…
Maximum Likelihood, Minimum Effort
John A. Smolin, Jay M. Gambetta, Graeme Smith
We provide an efficient method for computing the maximum likelihood mixed quantum state (with density matrix ) given a set of measurement outcome in a complete orthonormal opera…
Gaussian bosonic synergy: quantum communication via realistic channels of zero quantum capacity
Graeme Smith, John A. Smolin, Jon Yard
As with classical information, error-correcting codes enable reliable transmission of quantum information through noisy or lossy channels. In contrast to the classical theory, impe…
