What Quantum Computers Can Do Better Than Classical Computers
Quantum computers already outperform classical computers on a few specialized tasks, and over the coming years that list of tasks will grow. They excel at problems where superposition and entanglement let them explore a vast landscape of possibilities in parallel and use interference to extract an answer – factoring numbers,…

The Rise of Logical Qubits: How Quantum Computers Fight Errors
Logical qubits are the linchpin for delivering on the promise of quantum computing. They are the qubits as we wish we had them – long-lived and trustworthy – brought to life by the ingenuity of quantum error correction. By encoding information across many imperfect qubits, scientists have shown they can…

Quantum Programming: An In-Depth Introduction and Framework Comparison
Quantum programming is an emerging discipline that challenges developers to think beyond classical bits and deterministic algorithms. Instead of manipulating binary 0s and 1s, quantum programmers work with qubits that can exist in multiple states at once and harness phenomena like superposition and entanglement to perform computations in fundamentally new…

How Quantum Could Break Through Amdahl’s Law and Computing’s Limits
Amdahl’s Law teaches us a humbling lesson about the limits of classical computing: there is always a portion that resists parallel speedup, chaining us to diminishing returns. We’ve coped by clever engineering – making that chain as short as possible – but not broken it. Quantum computing offers a bolt…

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…

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…
