QC WORKSHOP 24: Introduction to Variational Quantum Circuit and Quantum Neural Networks

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”

QC WORKSHOP 21: Post Quantum Cryptography & bitcoin

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. NIST PQCContinue reading “QC WORKSHOP 21: Post Quantum Cryptography & bitcoin”

QC WORKSHOP 20: INTRO TO QUANTUM ERROR MITIGATION

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 recovering theContinue reading “QC WORKSHOP 20: INTRO TO QUANTUM ERROR MITIGATION”

QC WORKSHOP 19: Intro to Superconducting Qubits

In the community of superconducting qubit, Transmon is the most popular style of choice. It is easy to understand, fabricate and control.
