Quantum Computing: The Strange World of Phase
Open Source For You, Wednesday, September 16th, 2026
Third article in a quantum computing series explores quantum phase and its role in quantum operations.
This installment examines quantum phase through the Pauli-Y and Pauli-Z gates, demonstrating how phase affects quantum behavior despite being invisible in direct measurements.
Using Bloch sphere visualizations and Qiskit programs, the author shows how phase becomes observable through quantum interference.
The article debunks myths about quantum computers and explains hardware implementations in superconducting qubits, including Josephson junctions. Future articles will explore multi-qubit systems and quantum entanglement.
