Storing unitary operators in quantum states
We present a scheme to store unitary operators with self-inverse generators
in quantum states and a general circuit to retrieve them with definite success
probability. The continuous variable of the operator is stored in a
single-qubit state and the information about the kind of the operator is stored
in classical states with finite dimension. The probability of successful
retrieval is always 1/2 irrespective of the kind of the operator, which is
proved to be maximum. In case of failure, the result can be corrected with
additional quantum states. The retrieving circuit is almost as simple as that
which handles only the single-qubit rotations and CNOT as the basic operations.
An interactive way to transfer quantum dynamics, that is, to distribute
naturally copy-protected programs for quantum computers is also presented using
this scheme.Comment: 4 pages, 3 figures, errors in Eq. (8) and Fig. 3 are fixed, to appear

The Skin Antiseptic agents at Vaginal dElivery (SAVE) trial: study protocol for a randomized controlled trial
Background
Cleansing of the vulva and perineum is recommended during preparation for vaginal delivery, and special attention is paid to cleansing before episiotomy because episiotomy is known to increase the risk of perineal wound infection and/or dehiscence. However, the optimal method of perineal cleansing has not been established, including the choice of antiseptic agent. To address this issue, we designed a randomized controlled trial to examine whether skin preparation with chlorhexidine-alcohol is superior to povidone-iodine for the prevention of perineal wound infection after vaginal delivery.
Methods
In this multicenter randomized controlled trial, term pregnant women who plan to deliver vaginally after episiotomy will be enrolled. The participants will be randomly assigned to use antiseptic agents for perineal cleansing (povidone-iodine or chlorhexidine-alcohol). The primary outcome is superficial or deep perineal wound infection within 30 days after vaginal delivery. The secondary outcomes are the length of hospital stay, physician office visits, or hospital readmission for infection-related complications, endometritis, skin irritations, and allergic reactions.
Discussion
This study will be the first randomized controlled trial aiming to determine the optimal antiseptic agent for the prevention of perineal wound infections after vaginal delivery.
