Ancillary qubits work behind the scenes in quantum computing. They detect errors, enable complex gates, and support entanglement. Without them, reliable quantum operations would be impossible.
Google plans to build a computer that will require a freezer as large as a one-car garage. From there, researchers could start to run Shor’s algorithm at full power, exposing the secrets of our era.
Quantum-proof encryption introduces a set of algorithms that ensures protection for organizations of any size. Unfortunately, the current decade-old public key cryptography technology that many organizations rely on today will be broken and will not be able to withstand the deployment of quantum computers in the near future.
Quantum computers offer enormous potential to solve certain complex problems that are impossible for conventional computers, but this power depends on harnessing extremely fleeting behaviors of subatomic particles.
[A]ttention is turning towards quantum’s use as a tool for codifying quantitative macroeconomic problems, revealing how wealth evolves over time in response to changes or perturbations within the financial network..
[R]esearchers from Yokohama National University in Japan have found a way to precisely control qubits without the previous limitations.
For 25 years, QEC researchers have largely focused on mathematical strategies for encoding qubits and efficiently detecting errors in the encoded sets. Only recently have investigators begun to address the thorny question of how best to implement the full QEC feedback loop in real hardware…
The sixth part of an eight part-series by Mr. Russ Fein, founder of The Quantum Leap. In this work Russ provides a high-level overview of various types of qubits. The Quantum Leap is an up-and-coming blog journaling the race to quantum supremacy. Read the series here at The Qubit Report or find the complete series and more at, Quantumtech.blog.

A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit controls at room temperature. They built a series of compact radio frequency (RF) modules that mix signals to improve the reliability of control systems for superconducting quantum processors. Their tests proved that using modular design methods reduces the cost and size of traditional RF control systems while still delivering superior or comparable performance levels to those commercially available.
Researchers from the University of Bath have developed a technique for creating single-crystal flake devices so thin and pure that they may be able to outperform existing components for quantum computers.
