The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 07-23-aia AIA The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 07-21-aia AIA 5. Claim (s) 1-6, 8-17 and 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ramette et al. (US PG Pub No. 2022/0138608) in view of Frattini et al. (US PG Pub No. 2021/0021245) . 6. With respect to claim 1, Ramette teaches : A quantum computing system (see quantum computer, Abstract) , comprising: a set of qubits configured to be responsive to one or more microwave signals (see pair of qubits, Abstract; see set of qubits responsive to microwave transition, para 59-62) ; a control apparatus (see controller, para 46) configured to apply the one or more microwave signals to the set of qubits (controller to apply microwave signals, para 46 in conjunction with para 59-62) , the control apparatus including a set of control lines configured to transmit the one or more microwave signals to corresponding ones of the set of qubits (see controller, control portions for microwave tuning, para 45-49) ; a readout apparatus (see ultra-fast non-destructive readout for fast readout processing) configured to perform one or more measurements on the set of qubits (see measurements of qubits, Abstract; measuring photons, para 48; measuring qubit cavity, para 52) , the readout apparatus including a readout line operatively coupled to the set of qubits (see readout coupling, para 63-65) ; a paracoupler operatively arranged between the set of qubits and the readout apparatus, the paracoupler being configured to enable parametric fluorescent readout of the qubits via the readout apparatus, wherein when the paracoupler is not driven the paracoupler prevents coupling of the qubits with the readout line (see coupler coupled to detector, coupled via cavity modes for qubits, measuring qubits, fluorescence; parallelized fluorescence readout, para 52, para 96) . Ramette appears to be silent regarding: the coupler is a paracoupler [a parametric coupler and/or a multi-element coupler]. However, Frattini teaches: the coupler is a paracoupler [a parametric coupler and/or a multi-element coupler] (see connections for parametric coupling, para 13-16, 52-56) . It would have been obvious to one of ordinary skill in the art before the time of the invention to have incorporated Frattini’s paracoupler/parametric coupler/multi-element coupler into the invention of Ramette for at least the following reason(s): Frattini provides a paracoupling structure to process error-free readout for accurate measurement of qubit control values for improved quantum computing, thus providing a useful improvement to the quantum computing environment of Ramette. 7.

With respect to claim 10, Ramette teaches : wherein the one or more microwave signals comprise a set of microwave control pulses (see microwave pulses, para 48) . 15. With respect to claim 11, Ramette teaches : wherein one or more of the set of microwave control pulses comprise π-pulse, which acts to exchange populations of quantum states in the one or more qubits (see π-pulse, para 57) . 16. With respect to claim 12, Ramette teaches : A quantum computing method (see quantum computer, Abstract) , comprising: applying one or more microwave signals (see pair of qubits, Abstract; see set of qubits responsive to microwave transition, para 59-62) , by a control apparatus of a quantum computing system via a set of control lines, to selected ones of a set of qubits of the quantum computing system (see controller, para 46; controller to apply microwave signals, para 46 in conjunction with para 59-62, see controller, control portions for microwave tuning, para 45-49) ; enabling, by a paracoupler operatively arranged between the set of qubits and a readout apparatus, parametric fluorescent readout of the qubits (see coupler coupled to detector, coupled via cavity modes for qubits, measuring qubits, fluorescence; parallelized fluorescence readout, para 52, para 96) , wherein when the paracoupler is not driven the paracoupler prevents coupling of the qubits with a readout line of the readout apparatus (see ultra-fast non-destructive readout for fast readout processing, see measurements of qubits, Abstract; measuring photons, para 48; measuring qubit cavity, para 52) ; and performing, by the readout apparatus via the readout line, one or more measurements on the set of qubits based on the applied one or more microwave signals and the enabling of the paracoupler (see measurements of qubits, Abstract; measuring photons, para 48; measuring qubit cavity, para 52) . Ramette appears to be silent regarding: the coupler is a paracoupler [a parametric coupler and/or a multi-element coupler].
