Abstract
An assembly comprising a qubit and a method of altering a qubit, where a presence of a charge in a storage element close to the qubit influences on the state in which the altering is performed. Then, altering may be performed by feeding signals to electrodes, where the same signal is fed to the qubit but where the state is altered only if the charge is present in the storage element. Multiple qubits may then receive the same signal and only the ones with a charge are altered by the signal.

-15. (canceled)
An assembly comprising:
- a first qubit configured to hold one or more charged particles and being configured to represent each one of two states,
- one or more electrodes positioned so as to provide one or more electrical fields to the first qubit,
- a conditioning storage element having a centre positioned within a distance of 200 nm from a centre of the first qubit,
- one or more additional qubits each configured to hold one or more charged particles,
- means for converting a state of each additional qubit into a converted charge,
- a logical circuit configured to receive the converted charge(s) from the converting means and combine these into a resulting charge and provide the resulting charge to the conditioning storage element and
- means for repeatedly supplying a predetermined signal to each of the one or more electrodes so that:
- a) it brings the qubit to a first state by the supplying means feeding the predetermined signal to each of the one or more electrodes while the conditioning storage element comprises a first number of charged particles, and
- b) it brings the qubit to a second state by the supplying means feeding the predetermined signal to each of the one or more electrodes while the conditioning storage element comprises a second number of charged particles,
- wherein the first and second numbers of charged particles are different numbers of charged particles and wherein the first and second states/phases are different states/phases.
