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”

Quantum chemistry simulation is one of the most promising directions for achieving practical quantum advantage. For people interested in understanding the basic of quantum chemistry and its implementation, we start this three-lecture workshop. Through this workshop audiences will develop intuitions in the quantum mechanics and chemistry concepts. Such intuitions can be an anchor point forContinue reading “QC WORKSHOP 23: Quantum Chemstry jump starter”

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”

Recent years have witnessed the rapid development of various applications based on quantum information science. Among the many physical platforms, spin defect in diamond, namely nitrogen-vacancy (NV) centers, has attracted a lot of attention thanks to its good controllability and long coherence time even at room temperature. We will give a brief introduction to thisContinue reading “QC WORKSHOP 22: Spin defects in diamond for quantum applications”

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”
