Startup S-Transistors Builds Superconducting Transistors for Quantum Computers

Startup S-Transistors has proposed superconducting transistors based on Josephson junction field-effect transistors (JJFETs) that operate near absolute zero. This would allow control electronics to sit inside the cryostat, eliminating the complex wiring that currently penetrates it.

• Superconducting transistors operate at temperatures near absolute zero
• The design uses Josephson junctions (JJs) and JJFETs
• Control circuits could sit inside the cryostat, removing complex wiring
• S-Transistors claims it can now manufacture JJFETs at scale
