The interaction of matter and light is one of the fundamental processes occurring in nature,
and its most elementary form is realized when a single atom interacts with a single photon. …

We propose a realizable architecture using one-dimensional transmission line resonators to
reach the strong-coupling limit of cavity quantum electrodynamics in superconducting …

Short dephasing times pose one of the main challenges in realizing a quantum computer.
Different approaches have been devised to cure this problem for superconducting qubits, a …

Quantum-mechanical effects at the macroscopic level were first explored in Josephson-junction-based
superconducting circuits in the 1980s. In recent decades, the emergence of …

Superconducting circuits are promising candidates for constructing quantum bits (qubits) in a
quantum computer; single-qubit operations are now routine 1 , 2 , and several examples 3 , …

Quantum computers hold the promise of solving computational problems that are intractable
using conventional methods 1 . For fault-tolerant operation, quantum computers must …

Quantum computers, which harness the superposition and entanglement of physical states,
could outperform their classical counterparts in solving problems with technological impact—…

Using genome-wide approaches, we have elucidated the regulatory circuitry governed by
the XBP1 transcription factor, a key effector of the mammalian unfolded protein response (UPR…

Polycomb group proteins are critical to maintaining gene repression established during
Drosophila development. Part of this group forms the PRC2 complex containing Ez that …

We theoretically study single and two-qubit dynamics in the circuit QED architecture. We
focus on the current experimental design [Wallraff et al., Nature (London) 431, 162 (2004); …
