For use under QUnit, (or in general,) QBinaryDecisionTree now has a switch-over threshold from state vector as a more efficient alternative for narrower widths. To recover the original behavior, set the environment variable QRACK_BDT_THRESHOLD to 0. By default, binary decision tree methods will engage in QBinaryDecisionTree instances that are 31 qubits or greater in wifth, (equivalent to a QRACK_BDT_THRESHOLD of 30).
