The Race Toward FTQC: Ocelot, Majorana, Willow, Heron, Zuchongzhi
Quantum computing is entering a new phase marked by five major announcements from five quantum powerhouses—Amazon Web Services (AWS), Microsoft, Google, IBM, and Zuchongzhi—all in the last 4 months. Are these just hype-fueled announcements, or do they mark real progress toward useful, large-scale, fault-tolerant quantum computing—and perhaps signal an accelerated timeline…

Entropy-Driven Photonic Quantum Computing: A Critical Look at QCI’s Approach
Quantum Computing Inc. (QCI) has introduced an unconventional paradigm in quantum computing called Entropy Quantum Computing (EQC). Unlike the standard approach of isolating qubits in pristine, ultra-cold environments, QCI’s method intentionally embraces environmental noise and loss as part of the computation. Their quantum processors, optical devices operating at room temperature,…

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…

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,”…

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…

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…

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.…

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…

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.…

Quantum Technology Initiatives in Europe and EU
Europe’s quantum technology landscape has evolved from disparate academic projects into a coordinated multi-billion euro endeavor encompassing the EU and its member states. The historical commitment to quantum science is now manifesting in tangible outputs: prototype quantum computers in laboratories and supercomputing centers, quantum-secure communication testbeds linking cities, and quantum…
