The Benchmark Wars: Why Quantum Computers Can't Agree on a Yardstick
RafayelAsk a quantum computing company how good its machine is and you will get a number. The trouble is that no two companies quote the same number. One bra...
Circuit Knitting: Faking a Bigger Quantum Computer With Classical Glue
Every quantum processor has a hard ceiling: the number of qubits etched onto its chip. If your algorithm needs 40 qubits and your machine has 30, you...
The Heavy-Hex Lattice: Why IBM Gave Its Qubits Fewer Neighbors
Look at a photograph of an IBM quantum processor and you will notice something odd about the pattern. The qubits are not packed into a tidy square gri...
The Transmon Workhorse: Why Superconducting Circuits Dominate Quantum Computing
If you log into a quantum computer through a cloud service from IBM, Google, or Rigetti, odds are you are talking to a chip made of superconducting ci...
Reading the Roadmaps: What IBM, Google, and Quantinuum Promise
Almost every serious quantum computing company now publishes a roadmap. These are glossy diagrams with named chips, dated milestones, and confident ar...
What Quantum Computers Are Actually Useful For Right Now
Ask a vendor what their quantum computer can do and you will hear a long list: drug discovery, battery design, logistics, financial modeling, climate...
The Million-Qubit Problem: Why Quantum Computers Are Going Modular
For years the public story of quantum computing has been about one number climbing upward: the count of qubits packed onto a single chip. But the engi...
The Logical Qubit Race: How Error Correction Is Rewiring Quantum Hardware
For years the headline number in quantum computing was the qubit count. A chip with 50 qubits sounded more impressive than one with 20, and press rele...
