partial_trace R Documentation
Partial trace of a tensor product expression
Description
Assumes expr is a 2D square matrix representing a Kronecker product
of length(dims) subsystems. Returns the partial trace over the
subsystem at index axis (1-indexed).
Usage
partial_trace(expr, dims, axis = 1L)
Arguments
expr
An Expression (2D square matrix)
dims
Integer vector of subsystem dimensions
axis
Integer (1-indexed) subsystem to trace out
Value
An Expression representing the partial trace
