The experimental interest and developments in quantum spin-1/2 chains has increased uninterruptedly over the past decade. In many instances, the target quantum simulation belongs to the broader class of noninteracting fermionic models, constituting an important benchmark. In spite of this class being analytically efficiently tractable, no direct certification tool has yet been reported for it. In fact, in experiments, certification has almost exclusively relied on notions of quantum state tomography scaling very unfavorably with the system size. Here, we develop experimentally friendly fidelity witnesses for all pure fermionic Gaussian target states. Their expectation value yields a tight lower bound to the fidelity and can be measured efficiently. We derive witnesses in full generality in the Majorana-fermion representation and apply them to experimentally relevant spin-1/2 chains. Among others, we show how to efficiently certify strongly out-of-equilibrium dynamics in critical Ising chains. At the heart of the measurement scheme is a variant of importance sampling specially tailored to overlaps between covariance matrices. The method is shown to be robust against finite experimental-state infidelities.
Japanese police officers were welcomed aboard the air station courtesy of the Provost Marshall's Office Tuesday to participate in a guided tour of its facilities and training exhibits.
"This has become an annual sort of tour. Although last year, there was not nearly the amount of Marines participating in the demonstrations we had set up,"said Cpl. Michael A. Orozco, Headquarters and Headquarters Squadron crime prevention chief and native of Bakersfield, Calif.
Following the guided tour was a demonstration of the capabilities of military working dogs. The police officers were shown different scenarios that a military working dog unit might encounter and how its presence is vital.
"I've never seen a dog act so calm and able to respond to commands like the one today,"said Toru Seuehiro, senior police officer and native of Nagato City. "It makes me wish we were trained to work with such an animal."
The police officers later made their way to the pistol range here to witness some of its training exhibits. They were taken to an advanced simulation tank and shown how to operate its air-powered pistols. They were then taken through several scenarios that they might encounter as on-duty law enforcement personnel on the air station.
"The caliber of training Marines undergo is far more advanced than I have ever seen,"said Kiyonori Kurata, senior police officer and native of Shimono Seki City. "During (Japanese police) training, we fire 9mm blanks at an imaginary target. We get told our scenario and it is not right in front of us to see. This method (simulator) provides visual feedback and a more realistic simulation."
"Mostly, we do these tours to promote good will between our two jurisdictions,"said Orozco. "Being a good liaison is key. If they come here and see how we're running things, they'll know that we're on their side as well."
The police officers were all anxious for their chance to come aboard the air station according to Seuehiro. Each year, only a few senior police officers and those new police officers right out of school are able to participate in the tour. However, the number is quickly growing according to Orozco.
"This is an awesome environment. The training instruments are superb and every Marine seems to carry himself professionally,"said Kurata. "It seems that such an environment would make the job easier or maybe more enjoyable. I hope that if I don't give my spot to someone else, I can return next year."

The Surviving Opioid Overdose with Naloxone Education and Resuscitation (SOONER) study is a Toronto-based initiative in which individuals who were identified as being at high risk of experiencing or witnessing an opioid overdose were immersed into a high-fidelity simulated overdose. The primary objective of the SOONER study was to evaluate whether a novel point-of-care naloxone distribution and education strategy could lead to improved resuscitation outcomes compared to the current standard of care which involves a referral to a local pharmacy or naloxone distribution site [18, 19]. A randomized controlled trial was designed in which participants were allocated to either receive the point-of-care naloxone distribution strategy or the community referral strategy. Within two weeks of randomization, they were invited back to participate in a contextualized simulation in which their skills as a responder to opioid overdose were evaluated. The ability of participants to successfully resuscitate the mannikin (administer naloxone, perform CPR, etc.) was evaluated and their performance during simulation was used as the primary outcome measure for the SOONER study [18].
To our knowledge, SOONER is the first study to immerse a population who is specifically selected for their high likelihood of experiencing or witnessing an overdose in simulation. A unique opportunity is therefore created to try to understand what it is like for this population to participate in a high-fidelity simulated overdose. The purpose of this study is to describe the experience of participants with the simulation process in the SOONER study. The objective performance of participants during the simulated overdose represents the outcome measure of the SOONER study and will not be described in this paper. Rather, we seek to understand the perspectives and the subjective experience of participants with the simulation process.
This study employed a semi-structured debriefing interview and a follow up qualitative interview to understand the experience of participants in the SOONER trial [18]. It should be noted that the scope of this study pertained specifically to the experience of participants with the simulation process and that discussions that arose around broader themes such as addiction, stigma and rehabilitation are not described in this paper.
Demographic data for the 21 individuals who completed the SOONER study are presented in Table 1. The median age of participants was 43 and most participants identified as male (67%) and White (70%). Thirty three percent of participants reported living on the streets or in a shelter (33.3%) and over half of participants reported regular non-prescription opioid use (57%). Most participants endorsed previous experience with overdose having either witnessed (56%) or experienced an overdose themselves (33%). Less than half of the participants in our study identified having received formal CPR or opioid overdose education training (42.8%).
The briefing was a standardized video that oriented participants to the room and simulation scenario. It instructed them to respond as they would if the simulation were real and aimed to create a safe learning environment. A video briefing was chosen to ensure that study participant experience was as consistent and standardized as possible throughout the simulation (protocol in S1 Text).
A debriefing session was conducted by the research coordinator immediately following the simulation. Since no tool has been validated to lead a simulation debriefing with non-clinicians who have witnessed opioid overdoes, the Promoting Excellence and Reflective Learning in Simulation (PEARLS) framework was adapted to guide the debriefing. Developed by Eppich & Cheng in 2015 for use with healthcare learners, the PEARLS framework combines standard scripted language with an adaptable framework and designed to promote reflection of learning and performance [20]. Through facilitated discussion, participants were asked to self-assess their performance and reflect on their experience with simulation. During this debriefing session research coordinators affirmed positive behaviors, provided teaching, and offered an opportunity for participants to ask questions and clarify misunderstandings.
This study received ethics approval and ongoing oversight by the Research and Ethics Board of the Unity Health Toronto Research Ethics Board (REB), Toronto Public Health Research Ethics Board, and the University of Toronto Research Ethics Board (REB). A systematic review on strategies to improve informed consent processes found that having a one-to-one discussion was the most effective way of improving participant understanding of the research process. Verbal consent was therefore obtained from participants in a setting that afforded ample time for discussion and questions. Study coordinators then documented that they obtained verbal consent on the paper consent.
Data pertaining to the simulation experience were abstracted from 16 qualitative interviews and 21 debriefing sessions. A total of 284 transcript excerpts were identified that pertained to the experiences of participants with simulation. Qualitative content analysis identified 5 major themes and 17 subthemes and thematic saturation was achieved (Table 2).
