Optimal Bacon-Shor codes

We study the performance of Bacon-Shor codes, quantum subsystem codes which are well suited for applications to fault-tolerant quantum memory because the error syndrome can be extracted by performing two-qubit measurements. Assuming independent noise, we find the optimal block size in terms of the bit-flip error probability pX and the phase error probability pZ , and determine how the probabili...

Rediscovering Physics with BACON.3

BACON.3 is a production system that discovers empirical laws. The program uses a few simple heuristics to solve a broad range of tasks. These rules detect constancies and trends in data, and lead to the formulation of hypotheses and the definition of theoretical terms. BACON.3 represents data at varying levels of descr ipt ion, where the lowest have been directly observed and the highest corres...

Featherweight Monitors with Bacon Bits

Language-supported synchronization is a source of serious performance problems in Java programs. Even for single threaded programs the overhead of synchronization in compiled Java can be as high as 45%. I address this problem with a new language-level locking algorithm suitable for both uniprocessor and multiprocessor environments. On a Pentium uniprocessor, in the most common case the lock-and...
