Quantum information can be in a superposition of both 0 and 1 at the same time. Such qubits can be encoded in the polarization states of a photon or in the spin states of electrons and atomic nuclei. It can then be used to encode classical information.

…………………………………………

…………………………………………

Quantum information can be exchanged via entanglement. When two quantum systems or subatomic particles interact, they can get entangled. Once entangled, both systems are described by a single quantum state, so measuring the state of one system instantly influences the state of the other, even if they are kilometers apart.Once entanglement is distributed and established, the protocol to transfer qubits is robust and deterministic.

…………………………………………

A photon can be in a superposition of being emitted early or late.

…………………………………………

If quantum networks are to go intercontinental, entanglement will need to be distributed via satellites or drones.

Nowadays we can’t just live without some sort of computing power using powerful but pocket-sized devices.

…………………………………………

There is a limit to the miniaturisation of processor chips inside our powerful but pocket-sized computing devices.

…………………………………………

We can ignore the ‘classical’ size limits if we can tame quantum computing, a realm of complex numbers.

…………………………………………

Quantum computing ,in its full fledged version, will change life as we know it.

…………………………………………

The full potential for quantum computing is currently unknown.

…………………………………………

What appears to us as ‘computation’ is actually the controlled flow of electricity, i.e., “flow of electrons”.

…………………………………………

The smallest electronic switch or transistor is currently around 14 nanometres. Below a minimum scale limit, electrons turn their particle avatar into quantum probability wave and can no longer be switched on or off classically.

…………………………………………

In the sub-atomic world, electrons will be subject to the laws of quantum physics.

…………………………………………

Semiconductors ( transistors) are the building block of today’s computers.

…………………………………………

Quantum particles do not move in a straight line, but in a wavelike pattern in any direction.

…………………………………………

The informational unit of classical measurement values is a bit( 0 or 1). The informational unit of quantum measurement values is a Qbit( 0 and 1).

…………………………………………

Even one Qbit can represent multiple values. A traditional binary computer tackles two values simultaneously at the cost of speed. A quantum computer, however, would be able to work with hundreds simultaneously. This unlocks an unimaginable processing power.

…………………………………………

The proteins and molecules that make up living cells or medicines are governed by the laws of quantum physics.

…………………………………………

Classical simulation can’t predict the progression of a disease or the effectiveness of a medicine.

…………………………………………

Quantum simulation models can accurately mimic the behaviours of the proteins and molecules governed by the laws of quantum physics.

…………………………………………

In quantum internet, information could be shared without being transmitted.

…………………………………………

Distributing information via quantum entanglement is inherently secure. If someone tries to steal the information, it is instantly lost or broken.
