The heat transistor has an 'off' and an 'on' state. In the 'off' state an energy of e 2 /2 C is needed to add an electron to the island or to take one away (where e is the charge on the electron ...

A new type of transistor can dissipate almost zero heat — slashing energy usage in future quantum computers by up to 1,000 times and paving the way for massively scaled-up machines. The ...

Among its most promising advancements are quantum thermal diodes, which enable directional heat control, and quantum thermal transistors, which regulate heat flow with precision. Thermal diodes ...
