Gate model (quantum computing)
The gate model is a model of quantum computation in which an algorithm is a sequence of quantum logic gates acting on qubits, ending in a measurement.
Gate turn-off thyristor
A gate turn-off thyristor (GTO) is a power semiconductor switch, invented by General Electric in 1958, that can be turned off by a negative pulse at its gate.
Gate valve
A gate valve, also called a sluice valve, is a valve that starts or stops flow by sliding a flat gate across the passage, used fully open or fully closed.
Gate-all-around transistor
The gate-all-around (GAA) transistor is a field-effect transistor whose gate contacts the channel on all four sides, replacing the FinFET; Samsung first mass-produced it at 3 nm in 2022.
Gated Linear Attention
Gated Linear Attention (GLA) is a sequence-modeling layer extending linear attention with data-dependent gating, introduced by Songlin Yang and Yoon Kim's group in December 2023.
Gated recurrent unit
The gated recurrent unit (GRU) is a recurrent neural network cell introduced in 2014 by Kyunghyun Cho and colleagues as a streamlined alternative to the LSTM.
