Vector to Ket¶

This module is an ease of life adding to SageMath: it complements the latex method to quantum ket notations.

vector_to_ket.int_index_to_ket(index, register_size)[source]¶

Makes a int from a register into a binary ket notation. IMPORTANT: this notation requires the physics package in Latex

Example:

>>> int_index_to_ket(2,2)
'\\ket{10}'

Parameters:	index (int) – the index to be transformed register_size (int) – the number of qubits in the system
Returns:	string – a string in latex format

vector_to_ket.vector_to_ket(v)[source]¶

Transform a sage vector to a Latex ket notation

Example:

>>> v = vector(SR,[1,0,0,1])
>>> vector_to_ket(v)
1 \ket{00} + 1 \ket{11}

Parameters:	v (vector) – the vector corresponding to a pure state (size must be a power of two)
Returns:	str – a string corresponding to the Latex code for the ket notation of the input vector
