Quantum Computing

Take it or Leave it: U.S. National Security Agency Gave Us the Questions They Asked Themselves, and the Answers They Gave Themselves

Quantum computers can, in principle, perform certain mathematical algorithms exponentially faster than a classical computer. In place of ordinary bits used by today’s computers, quantum computers use “qubits” that behave and interact according to the laws of quantum mechanics. This quantum physics-based behavior would enable a sufficiently large-scale quantum computer to perform specific mathematical calculations that would be infeasible for any conventional computer.

Startup Funding August 2021

Quantum Brilliance received $9.7M in seed investment led by Main Sequence and founders of QxBranch, joined by CP Ventures, Investible, Jelix Ventures, MA Financial, R3I Ventures, and Ultratech Capital Partners. The startup uses synthetic diamonds to build quantum accelerators that do not require near absolute zero temperature or complex laser systems to operate with the goal of providing quantum accelerators the size of a lunchbox with over 50 qubits by 2025. Quantum Brilliance’s first product, a 5-qubit server rack-sized quantum accelerator, is now commercially available. It also offers a full stack of software and application tools. Based in Canberra, Australia, it was founded in 2019 as a spin-out from the Australian National University.

The Battle for Post-Quantum Security Will be Won by Agility

By Thomas Poeppelmann and Martin Schlaeffer
Due to their special features, quantum computers have the disruptive potential to replace existing conventional computers in many applications. They could, for example, calculate simulations of complex molecules for the chemical and pharmaceutical industry, perform complicated optimizations for the automotive and aviation industry, or create new findings from the analysis of complex financial data. At the same time, quantum computers also raise a lot of security concerns, and while today they don’t have real world applications, their capabilities are expected to grow significantly over the next 10 years. According to Michele Mosca, there is only a 14% chance that RSA2048 will be broken by 2026, but that grows to 50% by 2031. The security community has taken notice and is already preparing for quantum attacks.
