To explain superposition as briefly as possible is rather than a particle going through the top or bottom gate, it sends out beams that go through both gates at the same time. This is a very basic explanation and it is recommended you watch the video.

QTM1x The quantum Internet and quantum computers: how will they change the world?

# data[].attributes.body
The quantum internet, once functioning, will be extremely secure, and very well synchronized. The quantum internet allows that thing called entanglement to happen between two quantum computers from a massive distance. This will allow for things like major improvements in security and is extremely powerful for clock synchronization, which believe it or not, is actually one of the most important things for a computer.

To close off I am going to state that yes, quantum computers really do matter to us, even if none of the sciencey nerd stuff matters to you, the massive leap in security will matter.

A Qubit is like a traditional computer bit, which is a 0 or a 1, but what makes Qubits unique is that Qubits are a 0 and 1. This can sound very strange, what it means is when you run a quantum equation it runs X number of times and tells you how many times the bit was equal to a 0 or 1.

Qubit

A qubit (or quantum bit) is the quantum mechanical analogue of a classical bit. In classical computing the information is encoded in bits, where each bit can have the value zero or one. In quantum computing the information is encoded in qubits. A qubit is a two-level quantum system where the two basis qubit states are usually written as and . A qubit can be in state , or (unlike a classical bit) in a linear combination of both states. The name of this phenomenon is superposition. This video from the QuTech Academy explains some basic qubit properties.

Single-qubit computational basis states

The two orthogonal z-basis states of a qubit are defined as:

When we talk about the qubit basis states we implicitly refer to the z-basis states as the computational basis states.
The basis states are located at opposite points on the Bloch sphere representation of the state of a single qubit.

For more information see https://en.wikipedia.org/wiki/Bloch_sphere.

Qubit technologies

Several different physical implementations of qubits are possible. A number of examples are the polarizations of a photon, two of the (multiple) discrete energy levels of an ion, a superconducting Transmon qubit, the nuclear spin states of an atom or the spin states of an electron. Quantum Inspire is designed to control different qubit technologies. Its modular design allows it to re-use components that are technology independent while replacing components (software and hardware) that are technology dependent.

Above are an example of potential results running a quantum equation could give you. The results show how many times both bits were 0s and when both bits were 1s.

There is not enough space here for this to be fully explained, if you wish to know more follow the link above.

But in short: Quantum computing is a form of calculating equation by reading the polar direction of particles. This is extremely important for quantum mechanics and has been greatly advancing science. With quantum computers it may one day not too far from now, make spaceships like those seen in Star Wars or Star Trek. While we will probably never see a home quantum computer, because traditional ones are better at playing videogames and scrolling through social media (not even to mention the insane cooling arrays quantum computers take), it will still bring many improvements in other parts of our lives.

Quantum theory

Very small particles and light behave differently from objects we encounter in normal life, which are described by classical mechanics and classical electrodynamics. The mechanics of light and matter at the atomic and subatomic scale are described by quantum theory, which forms the underlying principles of chemistry and most of physics. In its first centennial of existence quantum theory has already brought us the information age with its disruptive technologies of transistors, lasers, nuclear power, and superconductivity.

But from the point of view of classical physics this theory can be seen as counter-intuitive or even bizarre. Quantum objects appear to be at two places at the same time, electrical currents in a metallic wire can flow clockwise and counter-clockwise at the same time, or an object can sometimes behave as wave and sometimes as particle.

Even a Nobel laureate like Richard Feynman struggled with the implications of quantum mechanics, which led to his famous quote:

I think I can safely say that nobody understands quantum mechanics - Richard Feynman

Although applications of quantum mechanics are not straight forward, this branch of physics opens up an entirely new world of possibilities in science, technology and information processing. One of the most promising ones is the quantum computer.

Quantum computers

A quantum computer is a device performing quantum computations. It manipulates the quantum states of qubits in a controlled way to perform algorithms. A universal quantum computer is defined as a machine that is able to adopt an arbitrary quantum state from an arbitrary input quantum state. The development of a quantum computer is currently in its infancy, systems consist of a few to a few tens of quantum bits (qubits). Main challenges in further development are to make the quantum computer scalable and to make it fault-tolerant. This means that it will be able to perform universal quantum operations using unreliable components.

In the last two decades of the previous century more and more quantum mechanical concepts were brought into information processing, allowing the development of so-called quantum algorithms. One of the early breakthroughs and still one of the strongest arguments for quantum computing to date is Shor's algorithm for integer factorization into primes. In many ways this algorithm can be seen as a starting signal. Since then the efforts in learning about what is required to build a quantum computer increased manifold.

Parallel to the theoretical efforts also ground-breaking strides were taken on the experimental side. Physicists developed methods to detect and controllably manipulate individual quantum objects such as photons, atoms or electrons. These quantum objects can obviously be used as physical implementations of qubits.

Challenges and opportunities

There are still many challenges in quantum computers and even more opportunities to explore. Scientists and engineers from QuTech in Delft, the Netherlands, are working hard to make quantum computing a reality. Significant progress is being made. Unlike the quantum computer prototype from Dilbert, our platform is ready to use. The platform consists of an extensive knowledge base, two actual quantum hardware chips, a quantum computer emulator and the editor to run your very real and very own quantum algorithms. Quantum Inspire is here, at your fingertips, to experiment, explore and enjoy!

Quantum computers also use entanglement, this states that particles, no matter the distance between them, correlates to the other particle. How a quantum computer uses this property is to calculate how often the particles correlate one way or the other.
