What does a quantum computer look like? That is what you are wondering, right? It may sound crazy, but the answer to that question is not so simple. Quantum computers have been in development for decades, and what they will eventually be able to do has yet to be seen. But what we can do now is show you what quantum computers might someday look like!

What is a Quantum computer?

A Quantum Computer is a machine that directly uses quantum mechanical phenomena such as superposition and entanglement to perform data operations. Quantum computers are primarily different from binary digital electronic computers based on transistors, but in theory, they can solve certain problems much more quickly using the same number of calculations while running with stable “qubits” (quantum bits) in a quantum state.

Qubits can be created from many different types of quantum systems, such as individual atoms, photons, electrons, or superconducting loops and wires. The most common qubit is the electron that exists in a spin-based quantum computer using computing elements made up of superconducting metals or semiconductors.

A quantum computer is what you would expect it to be if someone asked, “What does a normal computer look like?” They are typically housed in large metal cases with lots of lights and buttons. However, there are some key differences between what the average person thinks about computers and what they really do inside that make quantum computers what they are.  

The main difference is that the components in a quantum computer are much smaller, typically consisting of things like lasers and wires on microchips inside what looks to be an average desktop case with lots of lights and buttons. That isn’t too different from what most people expect from their normal laptops or desktops.

However, what is different about quantum computers compared to normal computers that might not be readily apparent in a typical case image is what’s going on inside.  

A typical computer processes information in small chunks, with each chunk representing something like a single number or letter from what we would consider binary data. Quantum bits of information can represent much more than just one bit of data.

They can hold what are called superpositions which means the bit of information is both one thing and another simultaneously, similar to how light can be seen as a wave or particle at any given instance by some experiments.  

This isn’t just limited to numbers either; it also holds true for all other types of digital information that computers process. For example, what we might think of as a single letter can be both an A and not-A at the same time. This indicates that quantum computers have the potential to hold exponentially more information than traditional computers can handle.

How is this useful? 

This could allow for things like incredibly detailed virtual reality simulations without any slowdown in performance or speed, or what we might consider artificial intelligence that actually works and can make predictions about what will be happening in the future based on what has happened before.

There is no one specific design for a quantum computer because they are such cutting-edge technology right now. However, there are things scientists know to look for if they want to build their own quantum computer or what they know about what makes a quantum computer work.

A quantum computer is what people are talking about when they mention a device that can process data in ways not possible with classical computers.

A quantum computer uses qubits, which are units of information analogous to the bits used by regular computers. However, unlike normal bits, where each bit represents either 0 or 1

How does Quantum Computers work?

A Quantum computer is a type of computer that utilizes the principles of quantum mechanics to perform operations. The development of this technology has given rise to, among others, quantum cryptography and Quantum key distribution protocols, which are also called QKD (Quantum Key Distribution). This is because it allows for secret messages or keys to be transferred in such a way that it is known if a third party has ever intercepted the message.

QKD works by using one or more single photons to carry information between two parties, Alice and Bob. The sender of the QKD encrypted message sends a series of 0’s and/or l’s (0 = no photon detected; i = detection) as binary data. This is then sent to the receiver, who can only decode it once they know which type of quantum operation was performed on the photon (i.e., polarization) and what settings were used in that process.

QKD allows for messages to be sent with provable security based upon information theory; however, QKD systems are susceptible to side-channel attacks. Quantum computers must be able to detect quantum states, and then the computer itself has a limited ability to influence that state through software or hardware operations. In order for data recovery from an unknown system state, one usually assumes some kind of classically probabilistic hidden variable theory while, in fact, there are strong mathematical proofs (Bell’s theorem, Kochen–Specker theorem, etc.) that no such theory can reproduce all quantum mechanical results. However, these proofs rely on the assumption of “free will”, which would be violated by a deterministic hidden variables model as in classical physics.

Many scientists believe it is necessary to introduce randomness into computing systems based on quantum mechanics, even if such randomness is merely perceived by humans.

QKD was first realized in 1989 between Pairs, France, and Vienna, Austria, over a distance of 143 km (89 miles). Since then, QKD has been used to create quantum networks that span several hundred kilometers.

Quantum computers are still largely in development but could overtake traditional computers in performance and speed.

Quantum cryptography is the process of using quantum mechanics to guarantee secure communication between two parties, where a third party cannot eavesdrop or intercept messages without detection, even if they can interfere with transmissions. This helps prevent traffic analysis which has been used for both spying and data mining.

A quantum computer operates on quantum bits or qubits rather than the traditional binary system of electronic computing. Qubits are able to take on a value of 0 and/or I simultaneously, which is known as superposition. This means that calculations can be done in parallel, unlike conventional computers, where each bit must be either 0 or 1 at any given time.

QKD is used to secure data transmitted through optical fiber channels. This technology is already being utilized in some banks, governments, and defense agencies for transferring or exchanging secret messages on an ultra-secure network between distant locations.

Quantum key distribution has been commercially available since 2005, when ID Quantique SA started selling QKD systems based upon major research institutions like the National University of Singapore.

QKD has been proven to be reliable and secure but is only suitable for small networks with short distances between nodes. This process provides security based upon quantum mechanics rather than purely on mathematics which can always eventually be broken down by more powerful computers.

Quantum computing could overtake traditional processing systems in performance any day due to its ability to perform parallel calculations, whereas traditional computing is limited by binary bits.

By the end of 2018, over 100 QKD networks will be commercially available and used for both data and money transfers on a global scale.
