单个超导涡旋存储比特逼近Landauer极限,但冷却与速度限制削弱优势

'Remarkably close to the minimum permitted by physics': this superconducting memory bit runs at an estimated 5x the limit, but at -269°C the fridge shrinks its claimed million-fold edge over today’s chips considerably

AI 导读

希伯来大学团队估算,单个超导涡旋存储比特在4.2 K、150 kHz下约可达到Landauer极限的五倍。论文称该结果基于连续驱动测量和数值分析,并未直接测量真实擦除,也未计入制冷能耗。设备还存在涡旋自行跳跃、数据保持时间短及论文评审争议等限制。
