Implementation of T gate optimization algorithm in reference https://arxiv.org/abs/1712.01557.
- Create a folder called "bin" in the directory of this readme file.
- Make sure GCC is installed and run "make all" in the TOpt directory.
A simple test can be execute by using:
make test
which uses the command:
./TOpt <command name> {-<option character> <option argument>}
e.g.
./TOpt circuit test.tfc -a todd -o output.sqc
The above command optimizes the circuit in file test.tfc using the TODD algorithm and saves the output circuit to output.sqc.
circuit Optimizes Clifford + T circuit. Takes as input .tfc file with path given by argument . See http://webhome.cs.uvic.ca/~dmaslov/mach-read.html for syntax description.
Options:
-a <algorithm>
Selects 3-STR solver where <algorithm> can take values the following values.
todd TODD algorithm.
tool TOOL algorithm. Has additional options:
-b <0|1> Without feedback|Feedback
-s <g|lg|r> Greedy|Least greedy|Random qubit order selection.
-r <integer> Sets n_RM to <integer>
re RE algorithm.
rm RM algorithm.
-o <filename>
If set, saves output circuit to file with path given by argument <filename> in deprocated .sqc format. Will implement code to output in .tfc format soon.
-v <0|1>
If argument is 1, TOpt will verify the functional equivalence of the input and output circuits using a brute force simulation of the quantum circuit.
-h <integer>
Sets cap on number of Hadamard ancillas to <integer>.
-c <filename>
If set, TOpt will add a row to the .csv file specified by the option value that contains data for the input circuit, optimization algorithm and output circuit. The row format is decribed in file "doc/csv_output_format.txt".
signature Optimizes a signature tensor. Takes as input .sig file with path given by argument . A .sig file is a sparse representation of the signature tensor with syntax as follows. First line must be n which sets the number of qubits of signature tensor, S. Remaining lines are of format a FOR S_{alpha,alpha,alpha}=1 OR b FOR S_{alpha,beta,beta}=S_{alpha,alpha,beta}=1 OR c FOR S_{alpha,beta,gamma} where each line indicates a value for which signature tensor element equals 1.
