“We have demonstrated a system composed of a single quantum dot in a cavity that can be used to realize ... This is only a fraction of the 180-degree rotation required to make a full logic gate, ...

Two papers in this week's edition of Science report on research using quantum dots—solid state qubits—to make both a simple quantum logic gate with a single qubit and a coupled dynamic system ...

How well do you know your logic gates? For their final submission for STEM Projects class, [BKriet] gamified the situation using a Raspberry Pi Pico, some blinkenlights, and a not-insignificant ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that ... Optical chirality, which is defined by left-handed and right-handed circularly polarized light, ...

For those just getting their start in digital logic, this teaching tool allows different logic gates to be wired together ... from a set of switches on the left to another set of LEDs on the ...

Quantum logic: Dolev Bluvstein (left) and Mikhail Lukin with their quantum processor ... experiments reached the milestone of using two logical qubits to operate a single quantum logic gate. In their ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...

Researchers at QuTech developed somersaulting spin qubits for universal quantum logic ... gates' are indeed possible, with state-of-the-art performance. Qubits based on quantum dots are studied ...
