Save as PDF. As an ST4 paediatric trainee or above or post completion paediatrician, you may wish to apply for a SPIN module.

This comprises additional training and experience in a clinical area. We have recently updated some of our SPIN modules, and have new SPIN modules in child mental health, audiovestibular medicine and oncology. Applications for SPIN are currently closed.

Last modified. Post date. Table of contents. About SPIN Types of SPIN List of SPIN modules Applying for SPIN and about the training Step 1 - Submit your application Step 2 - Evidence your SPIN Step 3 — Complete your SPIN Downloads.

About SPIN All SPIN modules are designed to enable a paediatrician to lead in that area as part of meeting a service need. The SPIN process is currently under review. Types of SPIN These are the types of SPIN offered by RCPCH: Progress training pathway: SPIN in training for Level 3 trainees - This is additional training and experience in a clinical area, which you complete in 12 to 18 months of clinical time.

If you do a SPIN module and complete your training, you can apply for posts as a General Paediatrician with a special expertise. Post completion SPIN for paediatricians on the GMC specialist register - This is additional training or experience, which you complete usually over a month to five-year period.

Pilot for specialty level paediatricians in child mental health, audiovestibular medicine and palliative medicine We are piloting a third type of SPIN, which is for doctors in paediatrics who are not in training positions nor consultant-level appointments. To demonstrate parity with the SPIN modules undertaken by trainees, you will need to evidence outcomes from these domains of the level 3 generic training curriculum, which you can see on our curriculum page : Communication Health promotion Leadership Quality improvement Safeguarding Research Your sign-off for these modules will be through review by the CSAC College Specialty Advisory Committee most connected to the specialty area of your SPIN.

uk List of SPIN modules Most SPIN modules have a framework of capability for SPIN or a SPIN module curriculum , which lists the requirements you need to demonstrate to complete the SPIN training.

When can I apply? When can I apply as a post-completion paediatrician? How long does the SPIN training take? Are the modules GMC accredited?

How do I get a SPIN placement during my training? How do I get a SPIN placement as a post-completion paediatrician or in the pilot phase for specialty level paediatrician?

Retrospective experience Trainees - You can request to count small amounts of retrospective evidence from your level 3 or Specialty training completed prior to your SPIN application. You must be undertaking the majority of your SPIN module prospectively and we cannot consider fully retrospective applications.

Post-completion paediatricians - If you are using retrospective evidence you must ensure that you describe what SPIN requirements you have already met and how you will maintain these while completing your SPIN. You will need to detail what requirements you have outstanding and how you will achieve these.

Indicatively, retrospective evidence older than five years is unlikely to be considered current enough for a SPIN module and should be commensurate with level 3 Progress Curriculum capabilities.

Specialty level paediatrician - the same rules apply as for post-completion requirements. The SPIN modules are also created to account for areas of the level 3 generic curriculum that must also be demonstrated for SPIN certification.

uk Step 1 - Submit your application All candidates complete the application form on RCPCH ePortfolio. The distance learning module 6 by BPNA is optional, as are PET2 and PET3. the RCPCH SPIN in Epilepsy can be completed without courses. Step 2 - Evidence your SPIN Trainees - When the CSAC has approved you to start your SPIN, we in the RCPCH will add the SPIN curriculum to your ePortfolio.

How long will my evidence be valid for? Diabetes only Retrospective experience is not accepted to count towards post completion SPIN modules in diabetes and applications must be prospective.

Step 3 — Complete your SPIN Once you complete your SPIN module and link your evidence via your ePortfolio, you will be able to complete the SPIN completion report and send to your SPIN supervisor.

How long will it take for my evidence to be reviewed? Competency frameworks and Progress aligned SPINs The competency frameworks apply to SPIN modules that are being revised and serve as an indicator of requirements.

Recent experiments have demonstrated long coherence times, high-fidelity operations, and long-range entanglement. However, control has so far been limited to a few qubits, with entangled states of three spins demonstrated.

Realizing larger multiqubit registers is challenging due to the need for quantum gates that avoid cross talk and protect the coherence of the complete register. In this paper, we present novel decoherence-protected gates that combine dynamical decoupling of an electron spin with selective phase-controlled driving of nuclear spins.

We use these gates to realize a ten-qubit quantum register consisting of the electron spin of a nitrogen-vacancy center and nine nuclear spins in diamond. We show that the register is fully connected by generating entanglement between all 45 possible qubit pairs and realize genuine multipartite entangled states with up to seven qubits.

Finally, we investigate the register as a multiqubit memory. We demonstrate the protection of an arbitrary single-qubit state for over 75 s—the longest reported for a single solid-state qubit—and show that two-qubit entanglement can be preserved for over 10 s.

Our results enable the control of large quantum registers with long coherence times and therefore open the door to advanced quantum algorithms and quantum networks with solid-state spin qubits.

The computational power of quantum networks is expected to far exceed that of classical technologies. Among the most promising quantum bits qubits for such networks are the spins of individual particles in solids, such as electrons and nuclei. Elementary control of such qubits and links within quantum networks have been demonstrated, but the largest entangled quantum states reported to date have contained just three spins.

Larger quantum registers are essential to realizing advanced computational power. However, controlling individual spins within complex and strongly interacting spin systems is a significant challenge.

In this study, we demonstrate a fully controllable ten-qubit register. Working at 3. We show that the system is fully connected by generating entangled states between all 45 possible spin pairs, and we prepare genuine seven-spin entanglement.

The spins that we study are excellent quantum memories that can store quantum states for up to one minute, the longest coherence time reported for solid-state spin qubits. We expect that our methods can also be applied to other spin platforms in diamond, silicon, and silicon carbide.

Our findings pave the way for advanced quantum algorithms and large multiqubit quantum networks based on tens of solid-state spin qubits. Illustration of the ten-qubit register developed in this work.

The electron spin of a single NV center in diamond acts as a central qubit and is connected by two-qubit gates to the intrinsic N 14 nuclear spin and a further eight C 13 nuclear spins surrounding the NV center.

b Illustration showing that the initial state of the electron spin determines which rf pulses are resonant with the nuclear spin. The phase of each rf pulse is adapted to create the desired nuclear spin evolution, accounting for periods of free precession according to Eq.

The final state vectors are antiparallel along the equator; therefore, the gate is a maximally entangling two-qubit gate.

By fitting the amplitude, we distinguish such deterministic phase shifts from loss of coherence due to entangling interactions.

Solid lines are fits to f φ. a Experimental sequence to prepare an electron-nuclear Bell state and determine the expectation value of the two-qubit operator Z X. A series of single- and two-qubit gates are used to initialize the nuclear spin [ 16, 37 ].

A measurement of the electron spin in the Z basis is followed by an X -basis measurement of the nuclear spin through the electron spin. These measurements are separated by a nuclear spin echo, which is implemented to mitigate dephasing of the nuclear spin.

The entire sequence is applied with and without an additional electron π pulse dashed box before the first electron readout in order to reconstruct the electron state while ensuring that the measurement does not disturb the nuclear spin state [ 16, 42 ].

The nuclear-nuclear correlations are well preserved after a nondestructive measurement of the electron spin in the X basis. Measured Bell state fidelities for all pairs of qubits in the ten-qubit register.
