Why are complex numbers needed in quantum mechanics? …
www.ind.ku.dkQuantum mechanics seems to use complex numbers in a more fundamental way. It su ces to look at some of the most basic equations, both in the matrix ([^p;x^] = i~) and wave (i~@ @t = H ^ ) formulations, to wonder about the presence of the imaginary unit. What is essentially di erent in quantum mechanics is that it deals with complex quantities ...
1 Complex Numbers in Quantum Mechanics
courses.physics.illinois.eduBottom line: In quantum mechanics, complex numbers are essential. 2 Photon Polarization, Probability and Interference in Quantum Mechanics The existence of polarized light gives a wonderful example where both classical ideas and one of the most puzzling features of quantum mechanics coexist. Polarization is very familiar in daily life.

THE CYBER PROJECT Quantum Computing and Cybersecurity
www.belfercenter.orgQuantum computing is a subfield of quantum information science— including quantum networking, quantum sensing, and quantum simulation—which harnesses the ability to generate and use quantum bits, or qubits. Quantum computers have the potential to solve certain problems much more quickly than conventional, or other classical, computers. They ...
