Silicon-Based Qubits Very Similar in Design to Classic Silicon Transistors
“Hot” spin quantum bits in silicon transistors Quantum bits (qubits) are the smallest units of information in a quantum computer. Currently, one of the biggest challenges in developing this kind of powerful computer is scalability. A research group at the University of Basel, working with the IBM Research Laboratory in Rüschlikon, has made a […]

6 Photons x 3 Degrees of Freedom = 18 Qubits of Entanglement
Renowned researcher, Pan Jianwei, lead a team of physicists from the University of Science and Technology of China with others from Alibaba’s Quantum Computing Laboratory. The research demonstrated entanglement of 6 photons, creating 18 qubits. The entanglements exploited three degrees of freedom encompassing their polarization, orbital angular momentum, and path. This nearly doubles the previous record of 10 entangled qubits.
