Colloquium: Multiparticle quantum superpositions and the quantum
... quantum information theory is rooted in the generation and transformation of quantum bits, or qubits, which are twodimensional quantum systems, each epitomized by a spin 12 (Nielsen and Chuang, 2000). A qubit, unlike a classical bit, can exist in a state ji that is a superposition of any two orthog ...

Superconducting Circuits and Quantum Computation—T. P. Orlando
... simple two-level system, observing such a gap would be unexpected for an incoherent transition, since the population in the lower level should always be larger than 0.5 in that case. In order to address this gap phenomenon in our multi-level system, a multi-level pump-decaying model is introduced. T ...

Introduction to Quantum Information Science
... Over the next decade Deutsch and others improved and discovered a few more quantum algorithms that were provably faster than the classical counterparts. However, the largest breakthrough came in 1994 when Shor developed a quantum algorithm that e ciently nds prime factors. The di culty in factoring ...

Power of Quantum Computation with Few Clean Qubits
... proposed are unexpectedly powerful and are able to simultaneously reduce both computation error and the number of necessary clean qubits, providing an almost fully satisfying solution in the cases of one-sided bounded error. In the two-sided-error case, the methods in this paper are applicable only ...

Quantum Money from Hidden Subspaces
... Aaronson [3] gave the first formal treatment of public-key quantum money, as well as related notions such as copy-protected quantum software. He proved that there exists a quantum oracle relative to which secure public-key quantum money is possible. Unfortunately, that result, though already involve ...
