Will Quantum Computers Replace Classical Computers?
No. Every quantum processor depends on classical computers to compile its programs, generate its control signals and read its results. Here's which jobs belong…
Public-Key and Symmetric Cryptography: Which Half a Quantum Computer Breaks
A quantum computer running Shor's algorithm would break RSA, Diffie-Hellman and elliptic-curve cryptography. AES and SHA-2 only lose some margin to Grover's algorithm. Here's…
What Quantum Computers Actually Do Better (And What They Don’t)
Four problem families where quantum computers have a real or plausible edge, ranked by the strength of the evidence, plus a screening test for…
What Quantum Computing Actually Is
The 'tries every answer at once' story is wrong, and it leads to the wrong investments. A plain account of qubits, interference, and the…
Quantum Parallelism: What “All at Once” Leaves Out
Superposition holds many states. Parallelism applies one operation to all of them. Interference decides what survives measurement, and that last step is the whole…
