Deriving noise eligibility from IBM calibration gate lengths fixed a wrong channel and left an uncompiled circuit with an empty noise model.
Dynamical decoupling reversed an apparent subthreshold trend for a surface code on IBM heavy-hex hardware. Here is the mechanism and the numbers.
A 1981 mainframe gives a symbol eight characters. Here is the include name three files had to share, and the 38 externals Assembler XF refused.
An IBM preprint composes post-selection with probabilistic error cancellation using a spacetime noise model, cutting inferred sampling overhead 63-fold.
A look inside the Open Memory Initiative's approach to building an open-source DDR4 UDIMM reference design, from architecture decisions to signal integrity.
