a two- state ( two- level) quantum- mechanical system

A qubit is a two- state ( two- level) quantum- mechanical system one of the simplest quantum systems displaying the peculiarity of quantum mechanics.

Source:

one of the smallest units of a quantum computing system

A qubit is one of the smallest units of a quantum computing system.

the quantum equivalent of the classical bit

A qubit is the quantum equivalent of the classical bit.

a unit of information that, unlike a binary unit (bit) used in classical computing architecture, can exist in a superposition of two states at once

A qubit is a unit of information that, unlike a binary unit (bit) used in classical computing architecture, can exist in a superposition of two states at once.

a unit of information analogous to a bit in classical computing (binary digit)

In quantum computing, a qubit is a unit of information analogous to a bit (binary digit) in classical computing, but it is affected by quantum mechanical properties such as superposition and entanglement which allow qubits to be in some ways more powerful than classical bits for some tasks.

Source:

a unit of information , described by a 'one'a 'zero', or a mixed 'superposition' of both states

A qubit is a unit of information described by a 'one', a 'zero', or a mixed 'superposition' of both states.

Source:

a unit of information , described by a “one”a “zero”, or a mixed “superposition” of both states

Remember, A qubit is a unit of information described by a “one”, a “zero”, or a mixed “superposition” of both states.

Source:

the analogue of a classical bit

A qubit is the analogue of a classical bit, but unlike a classical bit's classical counterpart, the quantum bit may be in a superposition of states.

Source:

a two-state quantum-mechanical system, such as the polarization of a single photon

A qubit is a two-state quantum-mechanical system, such as the polarization of a single photon: here the two states are vertical polarization and horizontal polarization.

a quantum system

A qubit is a quantum system, and this world has two possible states, kind of like a classic computer bit can be a 0 or a 1.

something's unit of information,

something's unit of information, the qubit, can be both 1 and 0 at the same time.

a quantum system that encodes 0 and 1 into two distinct quantum states

Well a qubit is a quantum system that encodes 0 and 1 into two distinct quantum states.

Source:

a unit of information described by a zero or a 1

A qubit is a unit of information described by a zero or a 1.

a unit of information which, unlike a ‘bit’ that expresses data in binary, can have any value between 0 and 1, or even both simultaneously

A ‘qubit’ is a unit of information which, unlike a ‘bit’ that expresses data in binary, can have any value between 0 and 1, or even both simultaneously.

a quantum two-level system that can be operated as a computational unit

A qubit is a quantum two-level system that can be operated as a computational unit.
