All-microwave leakage reduction units for quantum error correction with superconducting transmon qubits
J. F. Marques, H. Ali, B. M. Varbanov +9
Minimizing leakage from computational states is a challenge when using many-level systems like superconducting quantum circuits as qubits. We realize and extend the quantum-hardwar…
Generating Grid States From Schrödinger Cat States without Post-Selection
Daniel J. Weigand, Barbara M. Terhal
Grid (or comb) states are an interesting class of bosonic states introduced by Gottesman, Kitaev and Preskill to encode a qubit into an oscillator. A method to generate or `breed'…
Dispersive Qubit Measurement by Interferometry with Parametric Amplifiers
Sh. Barzanjeh, D. P. DiVincenzo, B. M. Terhal
We perform a detailed analysis of how an amplified interferometer can be used to enhance the quality of a dispersive qubit measurement, such as one performed on a superconducting t…
Qubit State Discrimination
M. E. Deconinck, B. M. Terhal
We show how one can solve the problem of discriminating between qubit states. We use the quantum state discrimination duality theorem and the Bloch sphere representation of qubits…
Single quantum querying of a database
B. M. Terhal, J. A. Smolin
We present a class of fast quantum algorithms, based on Bernstein and Vazirani's parity problem, that retrieve the entire contents of a quantum database in a single query. The…
