Physical qubit calibration on a directed acyclic graph

Autor: Kelly, Julian, O'Malley, Peter, Neeley, Matthew, Neven, Hartmut, Martinis, John M.

High-fidelity control of qubits requires precisely tuned control parameters. Typically, these parameters are found through a series of bootstrapped calibration experiments which successively acquire more accurate information about a physical qubit. H

Fabrication and Characterization of Aluminum Airbridges for Superconducting Microwave Circuits

Autor: Chen, Zijun, Megrant, Anthony, Kelly, Julian, Barends, Rami, Bochmann, Joerg, Chen, Yu, Chiaro, Ben, Dunsworth, Andrew, Jeffrey, Evan, Mutus, Joshua, O'Malley, Peter, Neill, Charles, Roushan, Pedram, Sank, Daniel, Vainsencher, Amit, Wenner, James, White, Theodore, Cleland, Andrew, Martinis, John

Superconducting microwave circuits based on coplanar waveguides (CPW) are susceptible to parasitic slotline modes which can lead to loss and decoherence. We motivate the use of superconducting airbridges as a reliable method for preventing the propag

Sputtered TiN films for superconducting coplanar waveguide resonators

Autor: Ohya, Shinobu, Chiaro, Ben, Megrant, Anthony, Neill, Charles, Barends, Rami, Chen, Yu, Kelly, Julian, Low, David, Mutus, Josh, O'Malley, Peter, Roushan, Pedram, Sank, Daniel, Vainsencher, Amit, Wenner, James, White, Theodore C., Yin, Yi, Schultz, B. D., Palmstrøm, Chris J, Mazin, Benjamin A., Cleland, Andrew N., Martinis, John M.

We present a systematic study of the properties of TiN films by varying the deposition conditions in an ultra-high-vacuum reactive magnetron sputtering chamber. By increasing the deposition pressure from 2 to 9 mTorr while keeping a nearly stoichiome

One of the most exciting potential applications of a quantum computer is the abilityto efficiently simulate quantum systems, a task that is out of the reach of even thelargest classical supercomputers. Such simulations require a quantum algorithm cap
