- Unanswered Questions
- How does this method compare to existing techniques for reducing gate counts in quantum circuits?
The article does not provide a direct comparison with other methods or techniques for reducing gate counts in quantum circuits. Further research or experimentation may be needed to evaluate the effectiveness of this approach in comparison to existing solutions.
- What are the specific conditions that need to be satisfied for erasing the ancilla qubit?
The abstract mentions erasing the ancilla qubit when a "first condition" is satisfied, but it does not specify what this condition entails. Additional details on the criteria for erasing the ancilla qubit would provide a clearer understanding of the method's operation.
Original Abstract Submitted
Methods, systems and apparatus for producing quantum circuits with low T gate counts. In one aspect, a method for performing a temporary logical AND operation on two control qubits includes the actions of obtaining an ancilla qubit in an A-state; computing a logical-AND of the two control qubits and storing the computed logical-AND in the state of the ancilla qubit, comprising replacing the A-state of the ancilla qubit with the logical-AND of the two control qubits; maintaining the ancilla qubit storing the logical-AND of the two controls until a first condition is satisfied; and erasing the ancilla qubit when the first condition is satisfied.
