China’s Quantum Computing and Quantum Technology Initiatives
In little over a decade, China transformed from a minor player into a quantum technology powerhouse. The talent has matured, and a new generation of Chinese quantum scientists is coming into its own – many trained at top universities domestically and abroad, now supported by some of the best facilities in the world. Looking forward, we can expect China’s quantum momentum to continue. The Chinese…

Quantum Technology Initiatives in Singapore and ASEAN
ASEAN’s journey in quantum technology is relatively recent but steadily gaining momentum. Singapore took the lead in the early 2000s – the National Research Foundation began funding quantum research as early as 2002, and by 2007 the government helped establish the Centre for Quantum Technologies (CQT) at the National University of Singapore. CQT was a milestone for the region, bringing together physicists, computer scientists, and…

Quantum Technologies and Quantum Computing in Russia
Russia’s engagement with quantum science dates back to the Soviet era, which produced a strong foundation of theoretical physics and early quantum experiments. This legacy endures in the modern era – Russian experts often note that the “Soviet school of quantum physics was one of the best in the world,” providing a deep talent pool for today’s initiatives. In the 2010s, Russia began explicitly organizing…

Variational Quantum Eigensolver (VQE) Breakthroughs
The Variational Quantum Eigensolver (VQE), introduced in 2014, has rapidly become a flagship algorithm for simulating ground-state properties on today’s noisy quantum computers. Rather than running long quantum circuits, VQE uses short circuits and a classical optimizer in tandem: the quantum processor prepares a trial wavefunction with adjustable parameters, and a classical computer iteratively tweaks those parameters to minimize the measured energy. This hybrid approach…

Quantum Contrarianism
Contrarianism in quantum tech, as in any tech, is best viewed as a tool, not a truth. It’s a tool for questioning and refining the narrative, for ensuring we don’t delude ourselves. But it is not the final truth of what the technology will or will not achieve – that truth will be revealed only through continued research, engineering, and yes, a bit of imagination.…

Quantum Technologies and Cybersecurity: Threats and Defenses
Quantum technologies introduce a new era for cybersecurity – one that is simultaneously perilous and full of potential. On the threat side, the advent of quantum computers threatens to upend the cryptographic protections we rely on daily, making it imperative that we transition to quantum-safe methods before quantum attackers emerge. At the same time, on the defense side, quantum physics offers unprecedented tools to achieve…

Quantum Computing Benchmarks: RCS, QV, AQ, and More
As quantum computing hardware rapidly improves, simple metrics like qubit count are no longer sufficient to gauge a system’s true capability. Unlike classical computers where transistor counts roughly correlate with performance, quantum bits (qubits) can be error-prone and short-lived, so a few high-fidelity qubits can be more valuable than many noisy ones. This has led researchers to develop specialized benchmarks that capture different aspects of…

Adiabatic Quantum (AQC) and Cyber (2024 Update)
Adiabatic Quantum Computing (AQC) is an alternative paradigm that uses an analog process based on the quantum adiabatic theorem. Instead of discrete gate operations, AQC involves slowly evolving a quantum system’s Hamiltonian such that it remains in its lowest-energy (ground) state, effectively “computing” the solution as the system’s final state. AQC and its practical subset known as quantum annealing are particularly geared toward solving optimization…
