Charge discreteness and the energy efficiency of information erasure in dynamic random-access memory cells
Takase Shimizu, Kouki Yamamoto, Kensaku Chida +2
A dynamic random-access memory (DRAM) cell stores information as an integer number of electrons on a capacitor, and whether this discreteness is thermodynamically relevant depends…
Strong intervalley mixing between copropagating quantum Hall edge channels in a silicon MOSFET
Gento Yamahata, Takase Shimizu
Copropagating quantum Hall edge channels provide a promising platform for compact electron interferometry and flying quantum states. In silicon, the valley degree of freedom offers…
Thermodynamic Constraints in Dynamic Random-Access Memory Cells: Experimental Verification of Energy Efficiency Limits in Information Erasure
Takase Shimizu, Kensaku Chida, Gento Yamahata +1
We measured the energy efficiency of information erasure using silicon DRAM cells capable of counting charges on capacitors at the single-electron level. Our measurements revealed…
Scalable Parallel Single-Electron Pumps in Silicon with Split-Source Control in the Nanoampere Regime
Gento Yamahata, Takase Shimizu, Katsuhiko Nishiguchi +1
Parallelizing single-electron pumps offers a promising route to achieving nanoampere-level currents crucial for quantum current standard applications. Achieving such current levels…
High frequency breakdown in quantum dots
Nathan Johnson, Gento Yamahata, Akira Fujiwara
Dynamic quantum dots are known to generate very accurate currents and can be used as a source of single electron wavepackets for use in quantum metrology, sensing or information pr…
