decoherence

[‚dē·kō′hir·əns]
(quantum mechanics)
The process whereby the quantum-mechanical state of any macroscopic system is rapidly correlated with that of its environment in such a way that no measurement on the system alone (without a simultaneous measurement of the complete state of the environment) can demonstrate any interference between two quantum states of the system.

Superconducting quantum circuits technology poses a series of important advantages, offering reduced decoherence and an improved scale up potential, being compatible with microwaves control circuits, operating with time scales of the nanosecond order [1].

The frisky "Decoherence" is a hilarious monologue about underwear as a measure of life's milestones and disappointments, marked by frequent harmonic changes and lightly percussive pianistic effects.
[[tau].sub.1] and [[tau].sub.2] have been introduced as the lifetimes of each state and [T.sub.d] is the decoherence time for the quantum superposition.

For these researchers, looking for ways to least delay decoherence - thereby preserving the state of superposition that makes quantum computers so much faster than their conventional counterparts - is a key goal.
From the quantum computing perspective, the error is mostly due to local decoherence or quantum noise.

The main advantage of the photonic implementation of qubits is the robustness against decoherence and the availability of one-qubit operations.
