BACKGROUND Quantum computing has undergone rapid development over recent years: from first conceptualization in the 1980s, and early proof of principles for hardware in the 2000s, quantum computers can now be built with hundreds of qubits. While the technology remains in its infancy, the fast progress of quantum hardware has led many to assert thatContinue reading “QC WORKSHOP 24: Introduction to Variational Quantum Circuit and Quantum Neural Networks”

BACKGROUND White house released NSM10 on May 4th of 2022, requiring whole USA to upgrade all IT digital systems, fundamental & critical infrastructure systems, military departments, intelligence systems, to quantum computer resistant cryptography from now on to 2035 as much as possible. This will also drive all cryptocurrencies, bitcoin including, to implement quantum resistant algorithms. NISTContinue reading “QC WORKSHOP 21: Post Quantum Cryptography & bitcoin”

BACKGROUND In the Noisy Intermediate-Scale Quantum (NISQ) era, we are limited by the number of qubits, coherence time, and gate fidelity. While Quantum Error Correction (QEC) is on its way, we still want to get meaningful results from such noisy quantum devices. It naturally introduces the idea of Error Mitigation (EM), which aims at recoveringContinue reading “QC WORKSHOP 20: INTRO TO QUANTUM ERROR MITIGATION”

BACKGROUND In the community of superconducting qubit, Transmon is the most popular style of choice. It is easy to understand, fabricate and control. Many famous companies, i.e. Google, IBM and Rigetti all use Transmon. However, it’s lifetime is typically limited to be below 100 μs. OUR SPEAKER Dr. Haozhi Wang is a postdoctoral researcher atContinue reading “QC WORKSHOP 19: Intro to Superconducting Qubits”

量子模拟是利用可控的量子系统去模拟待研究的量子系统，它可以作为一种有效的实验手段用于研究经典计算机难以计算的问题和实验条件无法观测的现象。量子模拟是量子计算最具潜力的方向之一。本次讲座将主要介绍量子模拟的基础知识、相关背景、可能应用以及相关算法和实现。 主讲人介绍： Qi Zhao is a QuICS Hartree Postdoctoral Fellow in quantum information science at the University of Maryland.
