The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

Hybrid quantum circuits combine two or more physical systems, with the goal of harnessing
the advantages and strengths of the different systems in order to better explore new …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

Qubits, the quantum mechanical bits required for quantum computing, must retain their
quantum states for times long enough to allow the information contained in them to be …

Quantum computers have the potential to solve certain problems faster than classical
computers. To exploit their power, it is necessary to perform interqubit operations and …

Carbon nanotubes are a versatile material in which many aspects of condensed matter
physics come together. Recent discoveries have uncovered new phenomena that …

We demonstrate improved operation of exchange-coupled semiconductor quantum dots by
substantially reducing the sensitivity of exchange operations to charge noise. The method …

Two level systems that can be reliably controlled and measured hold promise as qubits both
for metrology and for quantum information science. Since a fluctuating environment limits the …

One fundamental requirement for quantum computation is to carry out universal
manipulations of quantum bits at rates much faster than the qubit's rate of decoherence …

The similarities between gated quantum dots and the transistors in modern microelectronics,—
in fabrication methods, physical structure and voltage scales for manipulation—have led to …
