QX Rise v0.2.2

Release notes:

• Fixed bug in measurement and preparation implementation for large number of qubits.
• Fixed verbose GNU Compiler warnings under Linux.

QX Rise v0.2.1

Release notes:

• Enabled quantum noise simulation using the Depolarizing Error Model
• Added multishot simulation mode to save simulation time on the Quantum Inspire web platform.
• Enabled Identity gate support

The Depolarizing Error Model can be enabled by adding the following line o your cQASM code:
error_model depolarizing_channel,0.001 (where 0.001 is the error rate).

For more information on the depolarizing error model implementation please refer to the following paper:

QX Rise v0.2.0

Release notes:

• Initial cQASM 1.0 support.
• Integrated with libqasm 0.1.1 release.
• Added support for new quantum gates:
  • Flexible controlled phase shift (CR and CRK)
  • Measurement and Preparation in X/Y/Z basis: added measure_x, measure_y, prep_x and prep_y.
• Re-implemented classical NOT gate for full binary-controlled gate support.
• Added support for Single Gate Multiple Qubits (SGMQ).
• Fixed overflow bug when simulating more than 31 qubits.
• Fixed bug in qubit register measurement ("measure_all" instruction).
• Added a new set of unit tests.
