Satellite QKD

However, the next two years will see the launch of quantum satellites using a new protocol which solves all of the known problems of Satellite QKD. Those satellites will then take over the task of distributing the root source keys into data centres, and at that point the entire network end to end becomes fully quantum safe – in plenty of time before quantum computers are big enough to break RSA.

This revolutionary tech takes “root source” quantum keys that are stored in data centres and uses them as an ingredient in a novel process whereby two or more end point devices create symmetric encryption keys locally. This process is both zero trust and computationally secure. 

Today, the root source keys are created with quantum random number generators and sent to data centres globally using terrestrial digital methods. This is secure enough to allow the end point software to do its job in a very secure way.

It is believed RSA-2048, one of the most widely used forms of PKI encryption, could be cracked with as few as 2,000 logical qubits. At the rate the technology is developing, we anticipate this level of quantum computing being feasible within the decade, and perhaps in as little as five years.

We could talk about how exactly this works all day, but the result is a machine that makes the world’s best supercomputers look like pocket calculators.

One of the most striking examples is Google’s Sycamore, a quantum computer which completed a calculation so complex it is believed it would take IBM’s Summit, the most powerful supercomputer in the world, 10,000 years to solve.

This breakthrough occurred two years ago and the quantum computing field is moving incredibly quickly.

Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.

Cloud computing has the following benefits:

  1. Lower IT costs
  2. Improved agility and Time-To-Value
  3. Better scaling.

Quantum computers
  • Quantum computers are machines that use the properties of quantum physics to store data and perform computations.
  • Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a quantum bit or qubit. Qubits are made using physical systems, such as the spin of an electron or the orientation of a photon.
  • These systems can be in many different arrangements all at once, a property known as quantum superposition. Qubits can also be inextricably linked together using a phenomenon called quantum entanglement. The result is that a series of qubits can represent different things simultaneously.
