In fact, they effectively created the largest quantum register yet, with over 1,000 controllable sites.

Let us apply this to consider the real dimension of an m qubit quantum register.

Elements of act on a quantum register of qubits.

Suppose a single-qubit error occurs on the encoded quantum register.

The real dimension of the pure state space of an m qubit quantum register is 2 2.

Diamond quantum register developed.

This discovery is the basis for numerous applications of defects in diamond as single photon source, quantum register and in magnetometry.

The basic built-in quantum data type in QCL is the qureg (quantum register).

A quantum register (also known as a qregister) is the quantum mechanical analogue of a classical processor register.

A mathematical description of a quantum register is achieved by using a tensor product of qubit bra or ket vectors.

It has been shown that when the source of decoherence exhibits some symmetries, certain subsystems of the quantum register are unaffected by the interactions with the environment and are thus noiseless.

In brief, when a quantum register (a Hilbert space) is subjected to decoherence due to an interaction with an external and uncontrollable environment, information stored in the register is, in general, degraded.

In addition to a regular controlled NOT gate, one could construct a function-controlled NOT gate, which accepts an arbitrary number n+1 of qubits as input, where n+1 is greater than or equal to 2 (a quantum register).
