Quantum Computing

The future of accelerated computing is Quantum Computing. Current systems are now in production working in a hybrid environment with supercomputers. These systems show the potential of Quantum Computing to make a step-change in processing power for simulations, encryption and parallel computation applications.

New Quantum Computing simulators allow organisations to get a head start on coding and testing Quantum algorithms, to be ready to deploy on Quantum Computing hybrid platforms.

XENON has been at the forefront of accelerated computing since 1996, and with the XENON Quantum Computing simulation tools, you can start your work in Quantum Computing today.

What is Quantum Computing?

Quantum Computing uses qubits as the basis of computation. Qubits are quantum-mechanical systems, which exhibit the peculiar properties required for Quantum computing (e.g. electrons and their spin, photons and their polarisation, ions, atomic nuclei and their spin, SQUID devices, etc.). The unique features of qubits arise from the obscure world of quantum physics which makes them challenging to work with but also very powerful.

Qubits exist in a quantum state and have superposition – they can hold multiple values simultaneously until their actual state/value is measured. So a qubit can be positive (like a bit is a 1) or negative (which is like a bit being a zero), but quantum superposition means that qubits can also hold two states at the same time (say negative and positive for electron qubits). Superposition is a key feature of quantum mechanics and core to quantum computing.

The second unique feature of qubits in a quantum state is entanglement. This is where the states of two qubits are tied to each other (correlated/entangled)  and the value of one qubit then depends on the value of the other qubit. Then when the qubits are separated in space, the “entanglement” remains. When qubits are entangled, then measuring the value of one qubit instantaneously determines the value of the other (entangled) qubit. This is one of the paradoxes of quantum physics which is exploited in Quantum Computing.

This has obvious implication for parallel computing and the race is on to understand and manage quantum entanglement in a consistent, error-free way.

How will Quantum Computing impact us?

While Quantum Computing will be able to perform certain computing tasks faster, the parallel nature of entanglement makes quantum computing ideal for problems with large numbers of variables and simulations with large numbers of parameters. Problems like optimization and real-time adjustments to transport time-tables across multiple services (trains, trams, buses and ferries); encryption and cryptography, and AI and machine learning are all examples of problems that will suit Quantum Computing.

A large portion of the research into Quantum Computing is identifying what problems are best suited to Quantum applications. Quantum Computing simulators are an exciting way to test ideas and code to identify best use applications.

Challenges in Quantum Computing

There are number of companies advancing towards stable and reliable quantum computers now. The main challenges are scaling the number of qubits, stability, noise, and error correction. On top of that, there are many engineering challenges in designing and building Quantum Computers!
